Jack can read 45 pages of his book in one hour and a half hours. At that, how long will it take him to read the entire 300-page book?

Step-by-step explanation:

45 pages in 1.5 hours

90mins / 60mins = 1.5

45 / 1.5 = 30 pages in 1 hour

(30 pages per hour) * (x hours to complete book) = 300

30 pages * x hours = 300 pages

30x = 300

Divide both sides by 30 to get rid of the 30 and get the x on its own.

x = 300 / 30

x = 10

10 hours

Step-by-step explanation:

45 pages = 1½ hours

300 pages = x hours

X hours = (300 pages x1½ hours)/45pages

X hours = 10

The rate to complete the entire 300 pages is 10 hours
