Question

Lamar has a bucket of baseballs. While practicing, he uses 39 out of the 260 baseballs in the bucket in 15 minutes. At this rate, what fraction of the baseballs in the bucket will Lamar use in an hour?
A. 1/20
B. 9/20
C. 3/5
D. 5/4

Answer 1

ANSWER

C.$\frac{3}{5}$

EXPLANATION

If Lamar uses 39 baseballs in 15 minutes, then he will use 4×39=156 balls in 60 minutes.

This implies that, Lamar uses 156 baseballs in an hour.

The total number of balls in the bucket is 260.

In an hour, the fraction of the baseballs in the bucket will be:

$\frac{156}{260} = \frac{3}{5}$

The correct choice is C.
