Question

Steve burns 1,270 Calories of energy during a run that takes him 1.2 hours. Carol does the same run in 1.1 hours, but because she weighs less than Steve and runs more efficiently, she only burns 700 Calories. What is Carol's power for the run, compared to Steve's? Give your answer as Carol's power divided by Steve's power to two significant figures.

Answer 1

By using formula of power i.e.

Power = Energy / time, Carol's power for the run, compared to Steve's can be calculated.
