Question

If a snack cake contains 300 food Calories and Dr. Wallace is able to burn 150 Calories by rowing for one-half an hour, how long must he row to completely burn off the snack cake?

Question 13 options: 18 minutes 90 minutes No way to know 60 minutes

Answer 1

Dr. Wallace must row for 1 hour (60 minutes) to burn 300 Calories, as he burns 150 Calories in 30 minutes.

Step-by-step explanation:

If Dr. Wallace burns 150 Calories from rowing for one-half hour (30 minutes), we can calculate how long it will take him to burn off a snack cake with 300 Calories. Since he burns 150 Calories in 30 minutes, he would need to row for twice that amount of time to burn double the Calories.

Therefore, Dr. Wallace must row for 1 hour (60 minutes) to completely burn off a snack cake that contains 300 Calories.
