Answer: 2 chapters
Explanation:
You'll have to find the rate, so divide 5/1= 5 (this is how many times it's multiplied by) and divide 2 1/2 by 5
2.5 ÷ 5 = 0.5 = 1/2 of an hour
It takes you half an hour to read 1 chapter and since you need to find one hour, multiply 1x2
You can read 2 chapters in an hour
