Paul read 20 pages of a book in 15 minutes.
(a) What is Paul’s reading rate of pages per minute?
(b) If he continues to read at the same rate, how many pages will he read in 1 hour?

(a) Divide the number of pages (20) by the number of minutes (15).
(b) Multiply the rate from part (a) by 60 minutes. It should be four times longer than the number that he read in in 15 minutes.
