Answer:
A person can read 24 pages in 1/3 hour. There are 3 * 1/3 hours in 1 hour. So, the person can read 24 * 3 = 72 pages in one hour.
Step-by-step explanation:
20 minutes is 1/3rd of an hour. 24 pages / 20 minutes = 1.2 pages per minute. 60 minutes * 1.2 ppm = 72 pages per hour.
60/3=20
24/20 = 1.2
60*1.2=72
