The enthalpy change involved in the oxidation of glucose is -2880 kJ mol^-1 . Twenty five percent of this energy is available for muscular work. If 100 kJ of muscular work is needed to walk one kilomtere, what is the maximum distance that a person will be able to walk after eating 120 g of glucose?

The change in enthalpy due to combustion of glucose is 2880 " kJ mol"^(-1) . 25% of this energy is utilised by the body muscles to do physical work. If 100 kJ of energy is used by the muscles to walk 1 km then what will be the maximum distance a person can walk after consuming 120 g of glucose ?
