A cyclist trains by cycling for 3 hours at a constant rate on a
stationary bike. During this time she does mechanical work at a
rate of 100 W and loses heat to the environment at a rate of 300 W.
After training, she intends to eat enough chocolate to replace the
energy she has lost in the last three hours. A 100 g bar of
chocolate contains 2270 kJ of energy. How much chocolate should she
eat (in g)?
