Xiao Hong read 170 pages in 12 days, Xiao Ming read 240 pages in 17 days, Xiao Qiang read 27 or 28 pages, 300 pages. Who can read fast?
According to the knowledge of online literature enthusiasts, it was difficult to come up with a conclusion as to who read faster because everyone's progress was different at different times. Xiao Hong only reads 170 pages a day while Xiao Ming only reads 240 pages a day, which means that Xiao Hong is reading faster than Xiao Ming. However, Little Red only had 12 days while Little Ming had 17 days. Therefore, Little Ming had a longer reading time and progress. In addition, Cockroach read 300 pages between the ages of 27 and 8, which means that his speed may be faster than Xiao Hong and Xiao Ming. Therefore, it was impossible to simply answer the question of who read faster.
Xiao Hong read a book with 95 pages for five days. Xiao Li read this book with 30 pages a day. On average, how many pages did Xiao Hong read less than Xiao Li every day?
Xiao Hong spent a total of five days reading this book and had read a total of 95 pages. Xiaoli read 30 pages a day for a total of 5 days, so Xiaoli read a total of 30 × 5 = 150 pages. Then how many pages does Xiao Hong read less than Xiao Li on average every day? The total number of pages that Xiao Hong read was 95. The total number of pages that she read every day was 95/5 = 19. The total number of pages Xiao Li read was 30 x 5 = 150 pages. The total number of pages she read every day was 30 pages. This was because Xiao Hong read 19 - 30 = -1 pages less than Xiao Li every day. Therefore, Xiao Hong read an average of 19 pages less than Xiao Li every 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.
Xiao Dong read a storybook. He read 68 pages in the first 4 days and 72 pages in the next 3 days. How many pages did Xiao Dong read on average every day? The correct calculation was () A…
Xiao Dong read 68 pages in the first 4 days and 72 pages in the next 3 days, so the total number of pages in the book was 68+72+4*10=190 pages. How many pages does Xiao Dong read on average every day? How many days did Xiao Dong watch it? (Note: You need to add the first 4 days and the last 3 days to get the total number of days.) Xiao Dong reads an average number of pages per day = total pages/total days =190 pages/14 days =14 pages/day Therefore, Xiao Dong read an average of 14 pages a day. Therefore, he chose option A.
Xiao Dong read a storybook. He read 68 pages in the first 4 days and 72 pages in the next 3 days. How many pages did Xiao Dong read on average every day? The correct calculation was () A…
Xiao Dong read a storybook for a total of 68 pages in the first 4 days and 72 pages in the next 3 days, so the total number of pages read was:68+72+4*3=191 pages. How many pages does Xiao Dong read on average every day? It took Xiao Dong seven days to finish reading the book, so the average number of pages Xiao Dong read every day was 191/7=25 pages. Therefore, the correct calculation was page 25. The statement on page 20 of Item A was wrong. Page 17 of Item B and page 18 of Item C were all correct. Item D, page 26, is incorrect.
Xiao Dong read a storybook. He read 68 pages in the first four days and 72 pages in the next three days. How many pages does Xiao Dong read on average every day?
Assuming that the total number of pages Xiao Dong read every day was constant, then the average number of pages he read every day could be calculated by calculating the total number of pages in the first 4 days and the last 3 days. The total number of pages read in the first four days was 68, so Xiao Dong had read a total of 68 pages in these four days. The total number of pages he read in the next three days was 72 pages, so Xiao Dong read a total of 72 pages in these three days. Therefore, Xiao Dong had read a total of 68 + 72 + 10 + 2 = 190 pages in these 8 days. Divide the total number of pages by the total number of pages you read every day to get the answer to how many pages Xiao Dong reads on average every day: 190/8 = 225 pages The answer was 225 pages because Xiao Dong read an average of 225 pages a day.
A storybook had 156 pages. Xiao Ming read it for three days and there were still 12 pages left. How many pages does Xiao Ming read on average every day? [Solution to the equation]
Suppose Xiaoming reads an average of x pages every day: The total number of pages read in 3 days is:3 × 156 = 458 pages Look at the remaining pages:12 pages Therefore, the equation could be written: 458 - 12 = x + 156 Solve the equation: x = 220 Therefore, Xiao Ming reads an average of 220 pages a day.
Xiao Ming planned to read 36 pages a day, but he actually read 500 pages in 12 days. How many more pages did he actually read per day?
Xiao Ming planned to read 36 pages a day, but in fact, he read 500 pages in 12 days. 500 pages/12 days = 40 pages/day Because Xiao Ming reads 36 pages a day, the actual number of pages should be 40 pages more than the plan: 40 pages/day- 36 pages/day = 4 pages/day Therefore, Xiao Ming actually read four more pages of novels every day.
After-class reading. Xiao Ming read 69 pages of extra-cursory books in three days, and Xiao Min read 100 pages of extra-cursory books in five days. (1) How many pages of extra-cursory books does Xiao Ming read every day?（...
(1)How many pages does Xiao Ming read every day? Since the number of days Xiaoming and Xiaomin read is different, but the total number of pages they read is the same, we can assume that Xiaoming reads x pages of extra-cursory books every day: 3x = 69 Solution:x = 23 Therefore, Xiao Ming read 23 pages of extra-cursory books every day. (2)How many pages of books does Xiaomin read every day? Since the total number of pages Xiaomin reads is 100 and the number of days she reads is 5, we can assume that she reads y pages of extra-cursory books every day: 5y = 100 Solution:y = 1667 Therefore, Little Min read 1667 pages of extra-cursory books every day.
A book has a total of 150 pages, and Xiao Ming has already read 54 pages. The remaining pages are 8 pages a day, and it will take him a few days to finish them.
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.
Xiao Ming borrowed a 500-page novel and read 280 pages in the first 5 days. How many pages did he read on average every day?
Xiao Ming had read 280 pages in the past 5 days, so he had already read 280 x 5 = 1400 pages. The book has 500 pages, so the remaining pages are 500 - 1400 = -700 pages. This means that Xiaoming has to reread the 700 pages of the book in the next 7 days, but he can choose to start reading on any day. If Xiao Ming chose to start reading from the sixth day, then the number of pages he needed to read every day was 700/6 = 100 pages. Therefore, Xiao Ming needed to read 100 pages on average every day.
