(adsbygoogle = window.adsbygoogle || []).push({}); human energy problem!!

okay...i have this assignment that's due tomorrow morning so i'm begging for some help. There is only one problem that I'm totally lost on.

A 50 kg hiker climbs a mountain 1000m high in 3 hrs. Assuming the average O2 consumption during his climb was 2x10^-3 m^3/min(2 liters/min) corresponding to an energy expenditure of 4x10^4J/min, how much enery appears as heat in the body?

Any help would be great...Thanks so much!
