A quarter pound hamburger (115g) will rise the temp of 5kg of water 82.8 degrees C. A person uses about 100 Calories per mile when jogging. How many miles would a person need to jog to urn the Calories in one Hamburger?
• The heat released by the quarter pounder is:
heat = (1.00 kcal/kg.ºC)(5.00 kg)(82.8ºC) = 414 kcal
• 1 kcal is the same as 1 Cal, so we have
414 Cal/quarter-pounder
• If it takes 100 Cal / mile, you should be able to find the number of miles you can run on a quarter pounder.
