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.
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.
Lili finished reading a storybook in 8 days. She read 150 pages in the first 3 days. For the next 5 days, I read 42 pages a day. How many pages do I read on average every day?
Lili spent 8 days to finish reading a storybook. She read 150 pages in the first 3 days and 42 pages a day in the next 5 days. So she read a total of $150/times 3 + 42/times 5 = 2220$pages.

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 he read five more pages per day, the total number of pages per day would be 15 * 5/5 = 30 pages. The total number of pages that Xiao Ya needed to read in 20 days was 30 * 20 = 600 pages. If you read 15 pages a day, the total number of pages you need to read is 600 * 15/15 = 600 pages. Therefore, if you read five more pages a day, you can finish the book faster. The answer was: Ya-chan could finish the book in 15 days. She could read five more pages a day, and a total of 30 more pages, so she only needed 20-15=5 days to finish it.

No. Ling Ling read an average of 34 pages a day. It would take her 17 days to finish a 600-page story book. But because the storybook had 600 pages, it would take 17 days for Lingling to finish reading half of the storybook, which was 150 pages. Therefore, Ling Ling needed to read 34 pages/2=17 pages every day to finish the 150-page storybook in the 17th day.
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?
