A 68.0 kg person uses 214 kJ of energy to walk 1.00 km. This energy comes from “burning" glucose (Burning 1.00 g of glucose produces 15.7 kJ of heat.), but only about 30.0% of the heat of combustion of glucose can be used for propulsion. The rest is used for other bodily functions or is "wasted" as heat. Assuming that a "sugar-coated" breakfast cereal contains 29.0% sugar (which can be considered glucose) and no other energy source, calculate how many grams of cereal provide enough energy to walk 1.00 km.
