Question

Mollie had a 15–ounce cappuccino at her neighborhood coffee shop. The cappuccino had 170 calories. If Mollie walks for one hour, she burns 246 calories. For how many minutes must Mollie walk to burn off the calories in the cappuccino? (Round your answer to the nearest minute.)

Answer 1

41 mins

Explanation:

246 cal burned in 60 mins

1 cal burned in 60÷246 mins

Thus,

170 cal Burned in 170×(60÷246) mins

= 41.46 mins

round to 41 mins
