If he read five more pages per day, the total number of pages per day would be 15 * 5/5 = 30 pages. The total number of pages that Xiao Ya needed to read in 20 days was 30 * 20 = 600 pages. If you read 15 pages a day, the total number of pages you need to read is 600 * 15/15 = 600 pages. Therefore, if you read five more pages a day, you can finish the book faster. The answer was: Ya-chan could finish the book in 15 days. She could read five more pages a day, and a total of 30 more pages, so she only needed 20-15=5 days to finish it.

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.
