Question

stephen and alice are reading the same book. stephen reads 278 pages in 7 weeks. alice reads 31 pages each week. about how many more pages does stephen read each week than alice? 10 20 0 70

Explanation:

Step1: Estimate Stephen's weekly pages

To estimate how many pages Stephen reads per week, we can round 278 to 280 (since 278 is close to 280) and then divide by 7. So, $\frac{280}{7} = 40$. This is an estimate of Stephen's weekly page count.

Step2: Find the difference

Alice reads 31 pages per week. We estimate the difference between Stephen's weekly pages (40) and Alice's (31). $40 - 31 = 9$. Since 9 is closest to 10 among the given options, we can conclude that Stephen reads about 10 more pages each week than Alice.

Answer:

10
