mmmm well you know that if you burn 420 cal/hr at a rate of 15 mi/hr you are burning 28 cal/mi. The question now is what sort of function are you wanting to create? 

Let g(x) = 28x 

Where g(x) is a function of x (in miles) and its output is the number of calories burned over the given distance. 

Let h(t) = 420t 

Where h(t) is a function of t Iin hours) and its output is the number of calories burned over the given time. 

The list goes on.
