The linear function that models Rachel's distance as a function of time is:
D(x) = (70 mi/h)*x
<h3>
How to find a function that models Rachel's distance as a function of time?</h3>
Remember the relation between speed and distance:
Distance = Speed*Time.
Here we know that the speed of Rachel is 70 miles per hour, then if she drives for x hours, the distance traveled will be:
D(x) = (70 mi/h)*x
So we found a linear function that models Rachel's distance as a function of time.
