Question

Sarah exercised for 30 minutes. Kari exercised long

enough to burn 800 Calories. Who exercised for a longer
period of time, Sarah or Kari? Explain

Answer 1

Karl exercised longer - it takes the average person several hours to burn 800 calories, or an hour at least. If he really tried, he could feasibly do it in 40 minutes, but likely not less. This is an educated guess because the question doesn't give enough information.

Explanation:

Knowledge about the human body and how quickly we burn calories.
