Question

It took Trina 1 hour and 30 minutes to shovel the snow from her neighbor’s driveway. During that time she burned 630 calories. How many calories per minute did Trina burn shoveling snow?

Answer 1

Answer:

7

Step-by-step explanation:

The first step to solve this problem is to convert 1h 30min into just minutes. since there are 60 minutes in 1 hour you take 60 and add it ot the 30 extra minutes to get a total of 90.

Now, this question is asking you to find how many calories per minute she burns. When you are asked to find ___ per___ all you have to do is divide the first number by the second one. In this case you will divide calories by minutes.

630/90=7
