A book has 95 pages. Xiao Ming spent 4 days to read 32 pages, and the rest had to be finished in a week. How many pages does he read on average every day?
Xiao Ming spent 4 days to finish reading 32 pages, so the number of pages he read every day was: 32 pages/4 days = 8 pages/day Since the remaining book had 95 pages, he had to finish it within a week. 95 pages/8 pages/day = 12 days Therefore, Xiao Ming needed to read 12 pages a day to finish the remaining 95 pages in a week.

Dong Dong spent a week reading a storybook. He read 150 pages in the first three days and 200 pages in the next four days. We can use the formula of "A total of X pages in the previous N days, an average of Y pages per day" to calculate how many pages Dongdong reads on average per day: 1 Calculating the total number of pages in the first three days:150 pages/3 days = 50 pages/day 2. Total pages in the next four days:200 pages/4 days = 50 pages/day 3.

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.
There were 170 pages in a book. He read 12 pages a day, and after 13 days, there were only a few pages left.
A book has a total of 90 pages. After reading for 2 days, there are still 30 pages left. How many pages does Xiaohua read every day?
A book has a total of 90 pages. After reading it for two days, Little Light still has 30 pages left. 30 pages/2 days = 15 pages/day Because Little Light reads 15 pages of this book every day, the proportion of pages that Little Light reads every day is: 15/90 = 1/6 Therefore, Little Light read one-sixth of the book every day.
Little Ming read a book. He read 15 pages in the first 4 days and 6 pages a day in the next 5 days. How many pages did he read on average every day?
Xiao Ming read a book for the first 4 days and read 15 pages, then read 6 pages every day for 5 days. We can use the following formula to calculate the average number of pages seen per day: Average number of pages read per day = total number of pages/days Substituting the total number of pages and the number of days into the formula, we get: Average number of pages read per day = 15 pages/4 days = 3 pages/day Therefore, Xiao Ming read an average of three pages a day.
Xiao Ming read a book. He read 72 pages in the first 4 days and 29 pages a day for the next 6 days. How many pages did he read on average every day?
If Xiaoming reads 72 pages in the first 4 days, then Xiaoming's total page count in the first 4 days is 72 pages. Reading 29 pages every day for the next 6 days would mean that the total number of pages for the next 6 days would be 29 pages x 6 days = 171 pages. Therefore, Little Ming's total page count in the last six days was 171 pages. Little Ming read 171 pages per day for the next 6 days, 6 days = 27 pages. Therefore, Xiao Ming read an average of 27 pages a day.
Lili read a storybook. She read 78 pages in the first 3 days and 40 pages a day in the next 4 days. how much of this book
Assuming the book has a total of n pages, Lili read 78 pages in the first 3 days, then there are still n - 3 × 78 = n - 262 pages not read. In the next four days, she read an average of 40 pages a day. In these four days, Lili read a total of 40 × 4 = 160 pages. Therefore, Lili had read a total of n - 262 + 160 = 322 pages, just enough to finish the book. So this book had 322 pages.
