A 60.0-kg runner expends 300 W of power while running a marathon. Assuming that 10.0% of the energy is delivered to the muscle tissue and that the excess energy is removed from the body primarily be sweating, determine the volume of bodily fluid (assume it is water) lost per hour. (At 37.0 degrees Celsius, the latent heat of vaporization of water is 2.41 X 10^6 J/kg.)
