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. 1 1/3

b. 80

a. 20/15 = 1 1/3

b. 4 * 15 = 60 = 1 hour

Therefore multiply 20 * 4 = 80

To answer these questions, we need to first calculate Paul's reading rate of pages per minute and then use this rate to determine the number of pages he will read in 1 hour.

(a) To find Paul's reading rate of pages per minute, we divide the number of pages he read by the time it took him to read them. In this case, he read 20 pages in 15 minutes. So, we divide 20 by 15:

Reading rate = Number of pages / Time taken = 20 pages / 15 minutes ≈ 1.33 pages per minute

Therefore, Paul's reading rate is approximately 1.33 pages per minute.

(b) Now, to determine the number of pages Paul will read in 1 hour, we need to multiply his reading rate by the number of minutes in an hour. Since there are 60 minutes in an hour, we multiply the reading rate by 60:

Number of pages in 1 hour = Reading rate * Number of minutes in 1 hour = 1.33 pages per minute * 60 minutes = 79.8 pages

Therefore, if Paul continues to read at the same rate, he will read approximately 79.8 pages in 1 hour.
