The number of calories you burn depends on your weight. A 110​-pound person burns 163 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.

Respuesta :

163 / 110 = 1.48 calories / pound
1.48 × 190 = 281.2 calories / 30 minutes of tennis
