Jeff read 3/8 (three-eighths) of a chapter of his history book in 20 minutes. At this rate, how many chapters of his history book can he read in 1.5 hours? Explain how he got 27/16?

Answer 1

27/16 chapters completed in 1.5 hours

Explanation:

Jeff read 3/8 part in minutes = 20

He read complete chapter in minutes =
`(20)/((3)/(8))=(20)/(3) * 8 = (160)/(3) minutes`

60 minutes = 1 hour

`(160)/(3) minutes = (160)/(3) * (1)/(60)=(8)/(9) hours`

So, No. of chapters completed in
`(8)/(9)` hours = 1

No. of chapters completed in 1.5 hours =
`(1)/((8)/(9)) * 1.5=(27)/(16)`

So, 27/16 chapters completed in 1.5 hours
