Question

Allison can read 4 pages in 15 minutes. At this rate, how many pages can she read in an hour and a half?

Answer 1

In an hour and a half she can read 24 pages.

Answer 2

24

Explanation:

For 15 minutes to get into 90 minutes (half an hour) you must multiply by 6.

15*?=90 is the same as 90/15=?

90/15 is 6.

We must do the same with the 4 pages, which is to multiply by 6.

4*6 is 24.
