Question

Sara read 40 pages of a book in 60 minutes. How many pages should she be able to read in 90 minutes?

Answer 1

If Sarah read 40 pages in 60 minutes, this means that she can read 40/60=2/3 of a page in one minute. So in 90 minutes, she could read 90*2/3 = 60 pages.

 

40 pages / 60 minutes = 60 pages / 90 minutes
