Since the distance traveled is a function of the speed and time, then it is the distance formula as a function.

The distance formula is

*d*=*rt*So written as a function it would be

*f*(

*t*) = 3

*t*

*where f*(

*t*) =

*d*and the

*r*is the 3 mile per hour speed or rate.

Since the time is not given it is the variable data and the determining factor of each answer. For example, if you hiked for 2 hours, the distance you hiked would be

*f*(2) = 3x2 = 6 miles
