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

12(m-5) = 540

Explanation:

∵ The total calories have to burn = 540,

Also, here m represents the total time spent by Anzelm,

If he/she spent 5 minutes in rest,

Then the time he/she spent in jogging = (m - 5) minutes,

If the number of calories burnt in one minute = 12,

So, the number of calories burnt in (m-5) minutes = 12(m-5),

Therefore, for burning the whole calories,

Calories burnt by him/her = total calories

⇒ 12(m-5) = 540

Which is the required equation.

Answer 2

12(m -5) = 540

Explanation:

The left side of the equation is in the form of a product. A suitable product is ...

(calories/minute) × (minutes jogging) = (calories burned)

If m represent Anzelm's total minutes, then m-5 will represent the number of minutes actually jogging. This is what goes inside parentheses, so we have ...

(12 calories per minute) × ((m -5) minutes) = 540 calories

Leaving off the units, which we know are consistent, we have ...

12 (m -5) = 540
