A154-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.
