We were told that Stephen read 278 pages in 7 weeks. This means that the number of pages that Stephen reads in a week is
278/7 = 39.7
approximately 40 pages per week to the nearest ten
Alice reads 31 pages each week. If we round up to the nearest ten, it becomes 30 pages per week. Therefore, the difference between the number of pages that both of them read weekly is
40 - 30 = 10 pages
Therefore, Stephen reads 10 more pages each week than Alice.
