1. The problem statement, all variables and given/known data If a person radiates about 67 W of power at room temperature, how long does it take (h) for a person to radiate away the energy acquired by consuming a 285 Calorie donut? 2. Relevant equations i know W=J/s no clue, i need one that involves time. 3. The attempt at a solution i've tried 285/67=4.25 sec...but thats wrong... and i don't think the problem is asking in Kcals help?
