A 143 pound woman regularly exercises on a treadmill at speed of 5.5 mph and a 2.2% elevation. What is her caloric expenditure?

Question

I do not know which equation to use for this problem. 

Answer 1

This could easily be calculated however it would be highly inaccurate. To determine this we would usually measure oxygen consumption directly, or at least indirectly by measuring resting/maximal heart rate ; (thus reserve), to estimate metabolic equivalents and therefore caloric expenditure, in conjunction with other information provided)

If anyone is interested in simple physics answer however, please let me know and I’ll explain.
