Question

If I did 57 jumping jacks in 1 minute how long would it take to do 100 jumping jacks

Answer 1

Answer:

2 minuets

Step-by-step explanation:

Answer 2

Set up a ratio:

57 jumping jacks / 1 minute = 100 jumping jacks / x minutes

Cross multiply:

57x = 100

Divide both sides by 57:

X = 100/57

X = 1.754 minutes = 1 minute 45 seconds
