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.
To find Paul's reading rate (a), divide the number of pages he read by the time it took him to read them. So, Paul's reading rate is 20 pages / 15 minutes.
To find how many pages Paul will read in 1 hour (b), first convert 1 hour to minutes since his reading rate is in pages per minute. There are 60 minutes in 1 hour. Then, multiply Paul's reading rate by the number of minutes in 1 hour to get the number of pages he will read in that time. So, Paul will read (20 pages / 15 minutes) * 60 minutes.
