Question

To lose one pound of fat, a 200-pound person must burn 3,500 calories. If that person burns 180 calories by walking for 30 minutes, how many hours and minutes does the person have to walk to lose two pounds? Round your answer to the nearest minute.

A. 39 hours
B. 53 hours 38 minutes
C. 19 hours 27 minutes
D. 38 hours 53 minutes

Answer 1

C - 19 hours 27 minutes

Explanation:

180 × 2 = 360

360 calories in an hour

3500 × 2 = 7000 (amount of calories in 2 pounds)

7000 ÷ 360 = 19.4444...
