A 203 lb man eats an order of French Fries consuming 250 Cal of food energy. Afterwards he feels guilty and decides to work off the excess calories by walking up seven flights of stairs 3.0 times. (The total height of seven flights of steps is 110 ft) Calculate the energy the man has burned off by doing the exercise. Assume that work is done only when walking up the steps. Note: 1 Cal = 4.184 kJ

110ft= 33.528m

902.94*33.528*3=90 822J

90822J* 1Calorie/(4184J) = 21.7
