Scenario: There is a hiking trail near the town where Han and Jada live that starts at a parking lot and ends at a lake. Han and Jada both decide to hike from the parking lot to the lake and back, but they start their hikes at different times.
At the time that Han reaches the lake and starts to turn back, Jada is 0.6 miles away from the parking lot and hiking at a constant speed of 3.2 miles per hour toward the lake. Han’s distance, dd, from the parking lot can be expressed as d = − 2.4 t + 4.8, where tt represents the time in hours since he left the lake.

What is an equation for Jada’s distance from the parking lot as she heads toward the lake?
