will mark brainiest for the best answer and its worth a lot​

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
