However, it should be noted that reading speed varies from person to person. Some people may be able to read a lot of content in a short time, while others may need more time. Therefore, whether or not he could finish the book within the planned time needed to be evaluated based on his reading ability.

A book has a page, read 15 pages a day, and finish it in a week
A book has a page A. Reading 15 pages a day in a week is just enough. Assuming a book has page A and 15 pages a day, the number of days needed to finish the book in a week is: a ÷ 15 = (a + a) ÷ 2 = 2a / 2 + a / 2 Transferring items can be sorted out: 2a / 2 = a + a / 2 To simplify it: a = 4 Therefore, a book had four pages, and 15 pages a day was just enough to finish it in a week.

Uncle Wang planned to finish reading a 217-page novel in 15 days. He read a total of 112 pages in the first 8 days. How many pages does he read on average every day? Uncle Wang had read 112 pages in the first 8 days, so the total number of pages he needed to read in the remaining 15 days was: 15 days x 112 pages/day = 1656 pages Since he planned to finish the book in 15 days, the total number of pages he needed to read had to be a whole number.

A 600-page storybook. Nono would read 28 pages a day. Could he finish it in 19 days?
Reading 28 pages a day in 19 days can finish a 600-page storybook, but you need to pay attention to the following points: 1 The total number of pages in a storybook is 600, and reading 28 pages a day is actually only 28/2 = 14 days to finish reading each page. Therefore, he needed to divide 19 days by 14 days to determine the total number of pages he could read. The answer was that they could finish reading it, but they needed more time. If you read 28 pages a day, you would need 14 days to finish the story book. If Nono only reads 1 page in the remaining 14 days, she will not be able to finish the storybook. Therefore, Nono had to ensure that he could read a certain number of pages every day to ensure that he could read the entire story book. Reading 28 pages a day would take 14 days to finish a 600-page storybook. In the remaining 14 days, he had to ensure that he could read a certain number of pages every day in order to read the storybook completely.
