Michael reads 12 pages of a book in 18 minutes. If he reads at the same rate, how many pages will he read in 37 minutes?
Irina-Kira [14]

Answer:

Around 25 pages / 1.5 minute(s)

Step-by-step explanation:

18 / 12 = 1.5 minutes per paper.

So, 18 + 18 = 36 + 1 = 37 minutes

12 + 12 = 24 + 1 = 25

37 / 25 = 1.5
