Question

Phil consumed 1,200 calories at lunch. He has a goal of burning at least 5% of those calories by walking on the treadmill. If walking on the treadmill burns 200 calories per hour, which statement best describes how long he should walk on the treadmill?

Answer 1

5% of 1200 calories = 1200 × 0.05 = 60 calories

If one hour on the treadmill burns 200 calories and he only needs to burn 60 calories,

60 minutes ÷ 200 calories = 0.3 minutes needed to burn 1 calorie
0.3 × 60 = 18 minutes needed to burn 60 calories

  A. more than 18 minutes

~ B. no fewer than 18 minutes

  C. more than 3 hours
