Answer:

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.

___

In general, rates are related to quantities by ...

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

Answer:

well it would be c=420t but in reality it is just 420t

Step-by-step explanation:

They are only asking for two parts out of three. The 154-lb part is dropped from the equation leaving us with

  • [tex]x = (calories)*time[/tex] which is just the base.
  • [tex]C=420t[/tex] in simple terms is just the total calories over time.

C is calories, T is time; you're left with your starting base which is 420 calories per hour * the amount of time he spent biking.
