Answer:
Brock completed approximately 38 pull ups in the initial stage of training.
Step-by-step explanation:
We are given the following information in the question:
Ration of pull ups and box jumps initially =
Ration of pull ups and box jumps later =
Number of box jumps completed in the end of training = 53
Total number of exercises done in the end = 2x + 7x = 9x
We use the concept of ratio.
Initially,
Total number of exercise = 5y + 4y
Thus, he completed approximately 38 pull ups in the initial stage of training.
