Question

Rachel drives at a constant speed of 70 miles per hour.

Answer 1

The linear function that models Rachel's distance as a function of time is:

D(x) = (70 mi/h)*x

How to find a function that models Rachel's distance as a function of time?

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.
