Respuesta :
The answer is B. If he bounces the ball 25 times in 30 seconds, then write a proportion. 25/30 = x/150. Since 30 goes into 150 5 times, then 25 must go into x 5 times as well. So 5 x 5 = 125.
Answer:
B:125
Step-by-step explanation:
We can use a proportion to solve
25 times x times
------------- = -------------
30 seconds 150 seconds
Using cross products
25 * 150 = 30x
Divide each side by 30
25 * 150/30 = 30/30x
25 * 5 = x
125 times
