If Xiaoming reads a novel and reads 35 pages a day, he will finish the book one day later than the stipulated date. If he reads 40 pages a day, he will read 5 pages less on the last day…
Xiao Ming reads a novel. If he reads 35 pages a day, he will finish the whole book one day later than the stipulated date. If he reads 40 pages a day, he will read 5 pages less on the last day. We can set the total number of pages of the novel as x and the specified date as d, then the total number of pages that Xiaoming needs to read is x/35 + x/40 - 1. According to the question, Xiaoming needs to read d books, so there are: x/35 + x/40 - 1 = d Transferring the terms of the equation gave: x/100 = d Therefore, Xiao Ming needed to read 100 pages a day to finish the novel by the stipulated date. If you read 35 pages a day, you would need an extra two days to finish the novel. If you read 40 pages a day, you would need an extra three days to finish the novel. After considering all, Xiaoming needed to read 37 pages a day to finish the novel according to the stipulated date. On the last day, he had to read 5 pages less.
If Xiao Ming read 35 pages a day, he would finish the book one day later than the stipulated date. If he read 40 pages a day, he would have to read 5 pages less on the last day.
Xiaoming reads a novel. If he reads 35 pages a day, he will finish the book one day later than the stipulated date. If he reads 40 pages a day, he will read 5 pages less on the last day. Based on this information, we can formulate the following equation: Let the total number of pages in the novel be x Xiaoming reads x/35 days, that is, he reads x/35 pages every day. Because Xiao Ming needed to finish reading the entire book, he needed to meet the following two conditions: Xiaoming finished reading the novel before the stipulated date 2 Xiao Ming reads 35 pages a day, so the total number of pages read is 35x/12 days Therefore, we can write the following equation: x/35 = (x/12) - 1 Solve the equation: x = 35x/12 + 1 = 40 Therefore, Xiao Ming needed to read 40 pages to finish the novel. He needed to read 40/35=8/17 days before the specified date. However, because reading 40 pages a day is slower than reading 35 pages, the actual time he needs will be longer than 8/17 days, that is, he will need 16/17 days to finish reading the novel.
Xiao Ming reads a book. If he reads 15 pages a day, he will finish it in 24 days. If he reads 20 pages a day, how many days will he finish it?
If Xiao Ming reads 15 pages a day, the total number of pages he needs is: 15 pages/day x 24 days = 360 pages Therefore, Xiao Ming needed to read 360 pages to finish it in 24 days. The number of days required to read 20 pages a day is: 20 pages/day x days = 20 days Therefore, Xiao Ming needed to read for 20 days to finish the book.
If Little Ming reads a book, if he reads 15 pages a day, he will finish it in 24 days. If he reads 20 pages a day, how many days will he finish it?
If Xiao Ming reads a book every day for 15 pages and 24 days, then the book has a total of 15 * 24 = 360 pages. If I read 20 pages a day, how many days can I finish it? Assuming that the book has x pages, the total number of pages that Xiaoming needs to read is 20 * x days. Because Xiao Ming needed to read 360 pages, there were: 20 * x = 360 Solve this equation: x = 180 Therefore, Xiao Ming needed to read 180 pages to finish the book. If he read 20 pages a day, he would need 180 * 20 days = 3720 days to finish the book.
The number of pages that Xiaoming reads on the first day is 20% of the whole book. The next day, he reads 20% of the remaining pages. The number of pages that he reads on the second day accounts for 100% of the total pages of the whole book.
The number of pages that Xiaoming reads on the first day is 20% of the whole book. The number of pages that he reads on the second day is 20% of the remaining pages. The percentage of the number of pages that he reads on the second day can be calculated as follows: The number of pages that Xiaoming read on the first day was 20% of the entire book. In other words, the total number of pages that Xiaoming read was: Total pages = 20% × pages of the book = 02 × pages of the book The number of pages that Xiao Ming read the next day was 20% of the remaining pages. In other words, the total number of pages that Xiao Ming read was: Total pages = 20% x Remaining pages = 02 x Remaining pages Then, the percentage of the number of pages that Xiao Ming read the next day in the total number of pages in the book can be calculated as: The number of pages Xiao Ming read the next day divided by the total number of pages in the book × 100% = 02 divided by 08 × 100%= 25% Therefore, the number of pages that Xiao Ming read the next day accounted for about 25% of the total number of pages in the entire book.
Xiaoming reads a storybook. For the first 4 days, he reads 25 pages a day. After that, he reads 40 pages a day. After 6 days, he just finishes reading. How many pages does Xiaoming read per day on average?
Xiaoming reads a storybook for the first 4 days, reads 25 pages a day, then reads 40 pages a day, and reads for 6 days, just finishing it. How many pages does Xiaoming read on average every day? The number of pages in the storybook was fixed. The number of pages read in the first four days was 25 x 4 = 100 pages, and the remaining pages were 100 - 6 x 25 = 35 pages. Therefore, Xiaoming reads an average of 35 pages a day.
If Xiao Qiang reads a literary masterpiece, if he reads 20 pages a day, he can finish it in 18 days. If he reads 5 pages less a day, how many days can he finish it?
If you read 20 pages a day, you can read one literary masterpiece in 18 days, which is an average of 217 books per month. If you read five pages less a day, then it would take 10 days to read 15 pages a day, and it would take another 7 days to read 20 pages in 18 days.
Xiao Ming reads a novel, if he reads 35 pages a day,
If Xiao Ming reads 35 pages a day, then his reading speed is very fast. According to some studies, the average human can read about 200-300 pages a day, and some professional readers may read more. If Xiao Ming's reading speed could reach this level, he might gain more understanding and experience in the novel.
Xiaoming reads a book with 600 pages, planning to finish it in 10 days. In fact, he reads 30 pages less than planned every day. How long does Xiaoming actually take to finish it?
Xiao Ming read a book with 600 pages and planned to finish it in 10 days, so his daily reading plan was 600/10 = 60 pages. In fact, he read 30 pages less than he planned, so the number of pages that Xiaoming actually needed to read every day was 60 - 30 = 30 pages. Therefore, the number of days Xiaoming actually needed to read was 60 pages/30 pages/day = 2 days. Therefore, Little Ming actually needed two days to finish reading this book.
A 130-page novel, Xiaoming reads an average of four pages a day. Can he finish it in 28 days?
No. If Xiao Ming reads four pages of a novel every day, then it would take him 28 days to finish a 130-page novel because reading four pages a day would require a total of 130 pages, 4 = 35 pages. However, because the length of the novel was fixed, Xiaoming could not finish the book in 28 days, so the answer was no.
If Mao Mao reads a book and reads 30 pages a day, he can finish it in 8 days. If he reads 40 pages a day, how many days can he finish it in advance? Use the ratio method to answer
Mao Mao reads a book and reads 30 pages a day in 8 days. Therefore, the total number of pages in this book is 30 × 8 = 240 pages. If I read 40 pages a day, how many days can I finish it in advance? Using the ratio method to answer: To calculate the number of days you can read 40 pages a day compared to 30 pages a day, you can use the ratio method: Reading 40 pages a day was 40 - 30 = 10 pages more than reading 30 pages a day. Therefore, the number of days required to finish reading this book was 240 pages/10 pages/day = 240 days. Substituting this result into the original formula: 8 days/240 days = 0037125, which meant that reading 30 pages a day was about 37125 days earlier than reading 40 pages a day. Therefore, by reading 40 pages a day, he could advance by 0.037125 + 37125 = 47125 days. The answer was about four days in advance.
