18 pages a day, 14 days to read and play. If you finish reading it five days in advance, how many pages should you read every day?
If you read 18 pages a day, it would take you 14 days to finish it. If you want to finish the book 5 days earlier, you need to shorten the number of days to 10 days. 5 days earlier is equivalent to reading 18 pages less per day, so you need to read 24 pages per day (14 days-5 days =10 days).
Xiao Ya planned to finish reading a book in 20 days and read 15 pages a day. If he read five more pages a day, how many days would he be able to finish it?
If I read 30 pages a day, I can finish it 10 days earlier. If I read 15 pages a day, I can finish it 10 days later
The time spent reading a book depends on the number of pages you read each day. Reading 30 pages a day is 10 days slower than reading 15 pages a day. So if we were to read 30 pages a day, we would need to spend an extra 10 days on top of the original 10 days to finish the book. On the contrary, if we read 15 pages a day, we would need to spend an extra five days on top of the original 10 days to finish the book. So we can finish the book ten days earlier or ten days later, depending on the number of pages we choose to read and our reading speed.
A book is fifty pages thick. I read five pages a day. How many days does it take to finish reading it?
Xiao Ming planned to read a novel every few days. If he read 60 pages a day, he could finish it five days earlier. If he read 40 pages a day, he would have to finish it three days later.
Xiao Ming plans to read a novel every few days. If he reads 60 pages a day, he can finish it five days earlier. If he reads 40 pages a day, he will finish it three days later. Calculating how much faster reading 60 pages a day was than reading 40 pages a day: Reading 60 pages a day is better than reading 40 pages a day, reading 40 pages per hour, 60 pages = 067 hours Therefore, the total time Little Ming needed was: 1/067 = 1667(hours) 5 days ago 1667/067 = 28(hours) Days of delay Therefore, Xiao Ming needed 28 hours to finish reading this novel, which was longer than expected. Next, we can calculate the ratio of reading 60 pages a day to reading 40 pages a day, reading 40 pages per hour, reading 60 pages = 067 hours 's progress: Reading 60 pages a day is better than reading 40 pages a day. Reading 60 pages per hour/40 pages = 15 hours Therefore, the total time Little Ming needed was: 1 × 15 = 0667(hour) 5 days ago 0667/15 = 04(hours) Days of delay Therefore, Xiaoming needed four hours to finish reading this novel, which was shorter than the estimated time. To sum up, Xiaoming plans to read a novel every few days. If he reads 60 pages a day, he can finish it five days earlier. If he reads 40 pages a day, he will finish it three days later. If reading 60 pages a day was faster than reading 40 pages a day, reading 40 pages per hour, reading 60 pages per hour = 067 hours, the total time required was 1667 hours; if reading 60 pages a day was slower than reading 40 pages a day, reading 60 pages per hour, reading 60 pages per hour = 15 hours, the total time required was 0667 hours.
Li Ming was reading a 225-page novel. For the first five days, he would read 24 pages a day, and then 35 pages a day. How many more days would he need to finish this novel?
Li Ming read a 225-page novel. For the first five days, he read 24 pages a day and then 35 pages a day. The calculation is: 100 pages in the first 5 days, the remaining pages are 225-100=125 pages. Reading 24 pages a day required 125/24=5 days. Reading 35 pages a day required 125/35=4 days. Therefore, Li Ming needed 5+4=9 days to finish reading this novel.
Doudou would read 12 pages a day, and he could finish it in seven days. If I finish it in six days, how many pages will I read per day?
If Doudou could finish a book by reading 12 pages a day in 7 days, then the total number of pages would be: 12 pages/day x 7 days = 96 pages Therefore, the number of pages that Lil Pea needed to finish reading this book in six days was: 96 pages/6 days = 16 pages/day Therefore, Doudou had to read an average of 16 pages a day.
If Xiao Sen read 30 pages a day, he could finish it in 20 days. If he wanted to finish it in fifteen days, he would have to read forty pages a day.
If Xiao Sen read 30 pages of a literature book every day for 20 days, he could finish it. If he needed to read 40 pages a day to finish it in 15 days, then his reading speed should be 10 pages more per day. The calculations were as follows: 20 days x 30 pages/day = 600 pages 15 days x 40 pages/day = 600 pages Reading 10 more pages per day, the total number of pages required is 600 pages/(30 pages/day + 40 pages/day) = 600 pages/70 pages/day = 88 days Therefore, Xiao Sen needed to read 10 more pages every day, which was about 88 days, to finish reading this literary book.
Li Xiaolin was reading a storybook. If he read 12 pages a day, he would finish it in 15 days. If he had to finish it in 10 days, how many pages should he read on average every day?
If you can finish a storybook by reading 12 pages a day and 15 days, then the average number of pages in this storybook is: 15 days/ 12 pages/day = 15 pages/day Therefore, if Li Xiaolin wanted to finish reading this storybook in 10 days, he should read it on average every day: 10 days/ 15 pages/day = 6 pages/day In other words, Li Xiaolin should read 6 pages a day instead of 12 pages a day.
Little Light read 192 pages in three days, and he read 72 pages in three days. How many days can he finish reading at this speed?
Assuming that each page of the novel is 250 words long: 192 pages/250 words/page = 72 days Therefore, it would take Little Light 72 days to finish a 192-page novel at a rate of 72 pages a day.
Xiao Ming planned to finish reading a storybook in 16 days, which was an average of 15 pages per day. Now it takes 10 days to finish reading. How many pages should I read on average every day?
Xiao Ming planned to finish reading a storybook in 16 days. On average, he would read 15 pages a day. 16 days x 15 pages/day = 280 pages Now he needed 10 days to finish the book, so how many pages did he need to read every day? Assuming that Xiao Ming can finish reading the book in 10 days, the total number of pages he needs to read every day is: 10 days x 280 pages/day = 3000 pages Therefore, Xiao Ming needed to read 3000 pages per day on average, divided by 10 days = 300 pages per day.
