Question

The number of calories you burn depends on your weight. A 160​-pound person burns 237 calories during 30 minutes of tennis. Find the number of calories that a 190​-pound person would burn during the same​ activity, assuming they burn calories at the same rate.

Answer 1

A 190-pound person would burn 285 calories at the same rate.

Explanation:

Calories burn depends on the weight

Weight of first person = 160

Calories burn for 160 pounds in 30 mins = 237

Calories burn rate for 1 pound in 30 mins =
`(237)/(160)` = 1.5

Calories burn for 190 Pound person would be:

Weight of second person = 190

Calories burn for 190 pounds in 30 min:

As the burn rate of calories is same for the two persons:

= rate × weight

= 1.5 * 190

= 285 calories
