Today’s Riddles: December 19, 2010:

Walking Versus Running:
Since a person uses about the same amount of energy walking 2 miles as they would running for 2 miles, would a person use more energy running for 10 minutes, walking for ten minutes, or the same amount of energy?
Since a person running for 10 minutes would cover more distance than that same person would walking for 10 minutes, he would use more energy running for 10 minutes.
