Question

91. Jack can read 45 pages of his book in one and a

half hours. At that rate, how long will it take him to
read the entire 300-page book?

Answer 1

10 hours

Explanation:

45 pages per 1 hour and 30 minutes, or 60 min +30 min =90 min

90 minutes / 45 pages has to be equal to an equivalent fraction where we have 300 pages

90 minutes /45 pages = ? minutes / 300 pages , multiply both sides by 300

? minutes = 90*300/45 = 600 minutes

to read 300-page book will take 600 minutes = 10 hours
