Question

Anzelm wants to burn 540 calories while jogging. Jogging burns about 12 calories per minute. When Anzelm goes jogging, he usually plans to stop and rest for about 5 minutes.

Complete the equation below to find the total number of minutes (including rest) that Anzelm should plan to be out jogging. Use m to represent the total minutes.

Answer 1

Hi Johnnie,

In order to solve this problem, I set up the following equation:

(calories per minute burned)(number of minutes jogged - minutes rested) = (desired number of calories to burn)

12(m - 5) = 540

I put m - 5 instead of m because we have to take the 5 minutes of rest into account.

Now we just solve for m, which in this case, equals 50 minutes.

Anzelm should plan out 50 minutes for jogging.
