Answer:
c) Mike receives the award for being the best at jumping rope.
Step-by-step explanation:
Here, according to the question
Jumping rate of Linda = 120 times in 4 minute
So, number of jumps Linda does per minute = (120/4) = 30
So, Jumps per minute of Linda is 30.
Jumping rate of Carl = 315 times in 9 minute
So, number of jumps Carl does per minute = (315/9) = 35
So, Jumps per minute of Carl is 35.
Jumping rate of Mike = 252 times in 7 minute
So, number of jumps Mike does per minute = (252/7) = 36
So, Jumps per minute of Linda is 36.
Now if we compare the <u>jumps per minute</u> of Linda , Carl and Mike, weget that Mike has the best rate of 36 jumps per minute.
Hence, Mike receives the award for being the best at jumping rope.
