Problema Solution

On a bicycle, Amanda started 6 miles from her house, and rides 6 miles per hour away from her house.

Write an equation to model this situation (use m for miles and h for hours).

Answer provided by our tutors

let


v = 6 mph is the speed of Amanda

t = the time she travels in hours

f(t) the distance from her house as a function of the time t


At the beginning moment t = 0 hours she is 6 miles away from the house


t = 0 and f(0) = 6 miles


After t hours we have the following situation


f(t) = 6 + v*t


f(t) = 6 + 6*t


The equation f(t) = 6 + 6*t describes the travel of Amanda.
