A 154-lb person burns 420 calories per hour riding an exercise bicycle at a rate of 15 mi/h. Write a function rule to represent the total calories burned over time by that person.

c (t)

c is the number of calories burned. it is a function of time

c (t) = 420 * (t)

assuming we are measuring the 154lb person on a bicycle at 15 mi/h and we are measuring the time in hours.

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.
