Plzz answer 25 pts rated atar promise to give brainliest plzzz anyone know a 154-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.

c = 420t . . . . c is calories burned; t is hours riding at 15 mph

Step-by-step explanation:

There is not enough information given to write a function rule relating all the variables to calories burned. If we assume that calories are burned at the constant rate of 420 calories per hour, then total calories will be that rate multiplied by hours:

c = 420·t

where c is total calories burned by the 154-lb person, and t is hours riding at 15 mph.

quantity = rate · time . . . . . where the rate is (quantity)/(time period)
