Question

Part A
During one week, Charles swam for a total of 2.5h and walked for a total of 8.5 h. If Charles expends 340 kcal/h swimming and 160 kcal/h walking, how many total kilocalories did he expend for one week?
Express the energy in kilocalories to two significant figures.
total for one week =
kcal
Part B
If the loss of 3500 kcal is equal to a loss of 1.0 lb, for the amount of exercise that Charles did for one week in Part A, how much weight, in pounds, did he lose?
Express the energy in kilocalories to two significant figures.
weight loss in one week =
lb
