Question

Select the correct factor from the presentation and calculate how many pounds the person weighs if 75 calories are burned off. (round to the nearest pound.) a person jogs 1 mile in 8 minutes.

1) 121
2) 47
3) 49
4) 115

Answer 1

The person weighs approximately 49 pounds. Option C is answer.

Step-by-step explanation:

A person jogs 1 mile in 8 minutes, which means their jogging speed is 60 / 8 = 7.5 miles per hour.

Assuming the person burns 100 calories per mile, they burned 75 calories, which means they jogged 75 / 100 = 0.75 miles.

Since jogging burns 0.015 pounds per minute, the person burned 0.015 * 0.75 * 60 = 6.75 pounds while jogging.

Rounding to the nearest pound, the person weighs approximately 49 pounds. Option C is answer.
