Question

Grayson can read 18 pages of a book in 30 minutes. At that rate, how long would it take Grayson to read 150 pages? Express your answer in hours and minutes.

Answer 1

4 hours and 10 min

For this equation we will do ratios:

`(18)/(30) =(150)/(x) \\\\18x=4500\\x=250`

250 min =

4 hours and 10 min

4(60) = 240

240 + 10 = 250 minutes
