Final answer:
To find linear functions f and g that model the distances Jade and Jari travel as functions of time, use the equation x = xo + vt to calculate the displacements. Add the distances covered by Jade and Jari to find the total distance traveled.
Step-by-step explanation:
To find linear functions f and g that model the distances Jade and Jari travel as functions of time (t), we need to determine the equations for each function. Let's assume the linear equation for Jade is represented by f(t) and the linear equation for Jari is represented by g(t).
Since the problem provides data on the various legs of Jill's trip, we can calculate the displacements and elapsed time. We can use the equation x = xo + vt, where x is the position, xo is the initial position, v is the velocity, and t is the time.
To find the total distance traveled, we add up the distances covered by Jade and Jari. This can be done by finding the sum of the displacements of f(t) and g(t) over the given time.
