Question

Thomas went for a long hike and burned 657 calories in 2 1/2 hours. Marvin decided to go for a bike ride and burned 1,035 calories in 3 1/4 hours. Who burned the most calories per hour?

Answer 1

Answer:Marvin burned more calories per hour.

Step-by-step explanation:

Thomas went for a long hike and burned 657 calories in 2 1/2 hours. Converting 2 1/2 hours to improper fraction, it becomes 5/2 hours

This means that the amount of calories that Thomas burnt in 1 hour would be 657 × 2/5 = 262.8 calories per hour

Marvin decided to go for a bike ride and burned 1,035 calories in 3 1/4 hours. Converting 3 1/4 hours to improper fraction, it becomes 13/4 hours

This means that the amount of calories that Thomas burnt in 1 hour would be 1035 × 13/4 = 3363.75 calories per hour

Therefore, Marvin burns more calories per hour.
