Mary Beth could jump 42 times each minute. How many times could she jump in two hours explain to me step by step

5,040 jumps

Step-by-step explanation:

42 steps/minute * 60 minutes/hour = 2,520 jumps/hour

Mary Beth is jumping for 2 hours, so we need to multiply by 2 hours.

2,520 jumps/hour * 2 hours = 5,040 jumps
