A 61 kg collegiate cross-country athlete visits your exercise testing facility to see how many calories he burns on a normal training day. His measured VO2max is 71.2 ml/kg/min. You perform a submaximal aerobic test on him during his visit, and he achieves a steady state race pace VO2 of 64.5 ml/kg/min. How many calories would he burn in a race lasting 90 minutes? (Hint: choose the correct VO2 value for this question)
