Question

A person who weighs 240 pounds burns 180 calories per mile of running. If a person burns thirty-six calories by running one mile, how much does the person weigh?

Answer 1

Answer: 48 pounds

Explanation:

Given: A person who weighs 240 pounds burns 180 calories per mile of running.

There is a direct relation ship between the weight of the person and the calories burn.

If a person burns thirty-six calories by running one mile.

Let x be the weight of the person then

`(x)/(36)=(240)/(180)\\\Rightarrow\ x=(240*36)/(180)\\\Rightarrow\ x=48`

The weight of the person is 48 pounds.
