The rest of the books had to be finished in five days, so he had to read 125 pages a day.
The rest of the book had to be finished in the next five days, so he had to read 170 pages in total. I have already read 45 pages, so I need to read 125 pages a day (170 pages/5 days). Therefore, he read an average of 125 pages a day.
Xiao Gang needed to read an average of 30 pages a day to finish the remaining 170 pages in five days.
A book has 120 pages. If you only read 60 pages a day, you would need to read 120 pages/60 pages/day = 2 days. Therefore, he only needed two days to finish reading a book.
Xiao Ming had already read 54 pages and was reading 8 pages a day. Therefore, he still needed 8 × 7 = 56 days to finish reading the remaining pages.
For the remaining five days, he would need to read 180 pages- 80 pages = 100 pages every day. Therefore, he read an average of 100 pages a day.
Xiao Hong had already read 80 pages. The remaining pages were 200 - 80 = 120 pages. In order to finish reading the remaining 120 pages in six days, Little Red needed to read 120/6 = 20 pages every day. Therefore, Little Red read an average of 20 pages a day.
The remaining 5 days need to read 180 pages/5 = 36 pages/day Therefore, Xiaoxiao needed to read 36 pages on average every day.
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.
Assuming that the book has a total of x pages, then based on the 170 pages read in the previous 10 days, we can get: Day 1 - 10 days = 170 pages Day 2 - 11 = 180 pages Day 3 - 12 days ago = 190 pages Day 10-First 10 days = 170 pages Therefore, the book had a total of x pages that could list an equation: x = (170 + 180 + + 190) / 10 To simplify it: x = (1700 + 190n) / 10 Where n was the number of pages read on the 10th day. Because on the 10th day, I watched it for 8 days, so there were: n = 8 Substituting n into the above formula: x = (1700 + 190*8) / 10 x = (1700 + 1564) / 10 x = 2264 Therefore, this book had a total of 2264 pages.
