Question

Help Please! Please Explain.

Marissa jumped 42 times in 7 hours. At that rate, how many times would she jump in 30 minutes?

Answer 1

3

Explanation:

Well first let's calculate how many times she jumped per hour. For that we need to divide 42 by 7 which is 6. Now we need to divide that by two because they are asking for every half hour, not every hour. So 6 divided by 2 is 3. So our answer is 3.
