Question
A jogger ran 4 miles and then walked 2 miles. The average velocity running was 3 miles per hour faster than the average velocity walking. Express the total time for running and walking, T, as a function of the average velocity walking, x.
Step 1
The average velocity running is given as $x+3$ miles per hour. Therefore, the time taken to run 4 miles is $\frac{4}{x+3}$ hours. Show more…

A tourist drives 90 miles along a scenic highway and then takes a 5-mile walk along a hiking trail. The average velocity driving is nine times that while hiking. Express the total time for driving and hiking, $T,$ as a function of the average velocity on the hike, $x$.
Your average speed during a trip is 40 miles per hour. Write a linear function that models the distance you travel $d(t)$ as a function of $t,$ the time spent traveling.
