Answer:
The correct option is B
Leroy reads 22.5 pages in 30 minutes
At the rate of 3 pages in 4 minutes
Step-by-step explanation:
Given that Sam reads 30 pages of books in 40 minutes, he reads at the rate of 3 pages in 4 minutes (3/4 = 0.75).
To know which of the options has the same rate as Sam's, we need to find which rate is equal to his'
A. Francine reads 40 pages in 55 minutes
Rate = 40/55 = 8/11
B. Leroy reads 22.5 pages in 30 minutes
Rate = 22.5/30 = 0.75
C. Paul reads 150 pages in 3.25 hours. Since 3.25 hours = 195 minutes
Rate = 150/195 = 0.77
D. Bill reads 60 pages in 2 hours
Rate = 60/120 = 0.5
