Given:
154-lb person
burns 420 calories per hour when riding an exercise bicycle at a rate of 15mi/h

c(t) = 420t

this is the function that represents the total calories burned over time by that person. weight of the person and rate of the exercise bicycle is irrelevant in solving for the total calories burned.
