A154-lb person burns 420 calories per hour riding an exercise bicycle at a rate of 15 mi/hr. write a function rule to represent the total calories burned over time by that person. explain how the information in the problem relates to the function.

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.
