Question

At the beginning of every gym class, Mr. Gordon leads the class in a warm-up. In today’s warm-up, the class does jumping jacks for 3 minute. Erin does 54 jumping jacks in that time. Mr. Gordon says the class will do jumping jacks 4 minutes tomorrow. If Erin does jumping jacks at the same rate tomorrow, how many will she she do.

Answer 1

Answer:

Erin will do 72 jumping jacks.

Step-by-step explanation:

We divide 54 by 3 to get Erin's per minute ratio

She gets 18 jumping jacks per minute

We then add that to 54 to get her rate if she did for 4 minutes instead

The answer is 72
