How many kilocalories does a runner expend when he runs for 3.0 h and uses 620 Cal/h? How many pieces of pizza that each contain 13 g of protein, 15 g of fat, and 33 g of carbohydrates could be eaten after the race to replenish these Calories? (Do not round the total number of kcal to the appropriate signifcant figures when you report your answer. Round to the nearest whole slice of pizza.) [Hint: One gram of protein or one gram of carbohydrate typically releases about 4 Cal/g, while fat releases 9 Cal/g.] The runner expends kcal and can eat pieces of pizza.
