There are 75 pages in a book. Xiao Ming reads 9 pages every day. Can he finish it in a week? It'll take him at least a few days
There are 75 pages in a book. Xiaoming reads 9 pages a day for 7 days a week. Therefore, Xiao Ming read 9 pages a day, 7 pages a week, and a total of 75 pages. Xiaoming needed seven days to finish reading the 75 pages. Therefore, it takes Xiao Ming at least a few days to finish reading a book. The number of pages depends on the number of pages he reads every day. If he reads 9 pages a day, he needs 7 days to finish reading a 75-page book.
Xiao Ming reads a book. If he reads 15 pages a day, he will finish it in 24 days. If he reads 20 pages a day, how many days will he finish it?
If Xiao Ming reads 15 pages a day, the total number of pages he needs is: 15 pages/day x 24 days = 360 pages Therefore, Xiao Ming needed to read 360 pages to finish it in 24 days. The number of days required to read 20 pages a day is: 20 pages/day x days = 20 days Therefore, Xiao Ming needed to read for 20 days to finish the book.
If Little Ming reads a book, if he reads 15 pages a day, he will finish it in 24 days. If he reads 20 pages a day, how many days will he finish it?
If Xiao Ming reads a book every day for 15 pages and 24 days, then the book has a total of 15 * 24 = 360 pages. If I read 20 pages a day, how many days can I finish it? Assuming that the book has x pages, the total number of pages that Xiaoming needs to read is 20 * x days. Because Xiao Ming needed to read 360 pages, there were: 20 * x = 360 Solve this equation: x = 180 Therefore, Xiao Ming needed to read 180 pages to finish the book. If he read 20 pages a day, he would need 180 * 20 days = 3720 days to finish the book.
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 reads a book. He reads 1/13 of the book every day. After 4 days, there are 90 pages left. How many pages are there in this book?
Assuming that the book has $x$pages, the number of pages that Xiaoming reads on the fourth day is $x$multiplied by $1/13$. Because Xiao Ming had read for 4 days, the number of pages he read plus the remaining pages equals the total number of pages: $$ x + (x \times 1/13) + 90 = x $$ To simplify it: $$ x \times 12 - x \times 1/13 + 90 = 0 $$ Solve this equation: $$ x = 130 $$ Therefore, the book had a total of 130 pages.
If Xiao Qiang reads a literary masterpiece, if he reads 20 pages a day, he can finish it in 18 days. If he reads 5 pages less a day, how many days can he finish it?
If you read 20 pages a day, you can read one literary masterpiece in 18 days, which is an average of 217 books per month. If you read five pages less a day, then it would take 10 days to read 15 pages a day, and it would take another 7 days to read 20 pages in 18 days.
Xiaoming reads a book with 600 pages, planning to finish it in 10 days. In fact, he reads 30 pages less than planned every day. How long does Xiaoming actually take to finish it?
Xiao Ming read a book with 600 pages and planned to finish it in 10 days, so his daily reading plan was 600/10 = 60 pages. In fact, he read 30 pages less than he planned, so the number of pages that Xiaoming actually needed to read every day was 60 - 30 = 30 pages. Therefore, the number of days Xiaoming actually needed to read was 60 pages/30 pages/day = 2 days. Therefore, Little Ming actually needed two days to finish reading this book.
If Mao Mao reads a book and reads 30 pages a day, he can finish it in 8 days. If he reads 40 pages a day, how many days can he finish it in advance? Use the ratio method to answer
Mao Mao reads a book and reads 30 pages a day in 8 days. Therefore, the total number of pages in this book is 30 × 8 = 240 pages. If I read 40 pages a day, how many days can I finish it in advance? Using the ratio method to answer: To calculate the number of days you can read 40 pages a day compared to 30 pages a day, you can use the ratio method: Reading 40 pages a day was 40 - 30 = 10 pages more than reading 30 pages a day. Therefore, the number of days required to finish reading this book was 240 pages/10 pages/day = 240 days. Substituting this result into the original formula: 8 days/240 days = 0037125, which meant that reading 30 pages a day was about 37125 days earlier than reading 40 pages a day. Therefore, by reading 40 pages a day, he could advance by 0.037125 + 37125 = 47125 days. The answer was about four days in advance.
Xiao Ming planned to read a novel every few days. If he read 60 pages a day, he could finish it five days earlier. If he read 40 pages a day, he would have to finish it three days later.
Xiao Ming plans to read a novel every few days. If he reads 60 pages a day, he can finish it five days earlier. If he reads 40 pages a day, he will finish it three days later. Calculating how much faster reading 60 pages a day was than reading 40 pages a day: Reading 60 pages a day is better than reading 40 pages a day, reading 40 pages per hour, 60 pages = 067 hours Therefore, the total time Little Ming needed was: 1/067 = 1667(hours) 5 days ago 1667/067 = 28(hours) Days of delay Therefore, Xiao Ming needed 28 hours to finish reading this novel, which was longer than expected. Next, we can calculate the ratio of reading 60 pages a day to reading 40 pages a day, reading 40 pages per hour, reading 60 pages = 067 hours 's progress: Reading 60 pages a day is better than reading 40 pages a day. Reading 60 pages per hour/40 pages = 15 hours Therefore, the total time Little Ming needed was: 1 × 15 = 0667(hour) 5 days ago 0667/15 = 04(hours) Days of delay Therefore, Xiaoming needed four hours to finish reading this novel, which was shorter than the estimated time. To sum up, Xiaoming plans to read a novel every few days. If he reads 60 pages a day, he can finish it five days earlier. If he reads 40 pages a day, he will finish it three days later. If reading 60 pages a day was faster than reading 40 pages a day, reading 40 pages per hour, reading 60 pages per hour = 067 hours, the total time required was 1667 hours; if reading 60 pages a day was slower than reading 40 pages a day, reading 60 pages per hour, reading 60 pages per hour = 15 hours, the total time required was 0667 hours.
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 Ming reads a novel, if he reads 35 pages a day,
If Xiao Ming reads 35 pages a day, then his reading speed is very fast. According to some studies, the average human can read about 200-300 pages a day, and some professional readers may read more. If Xiao Ming's reading speed could reach this level, he might gain more understanding and experience in the novel.
