Answer:
Distance between Alan and Alissa (ft/s)
Time (s)
Step-by-step explanation:
In this example, since Alan and Alissa are both traveling at a constant rate, their velocity is not a varying quantity. However, the distance between Alan and Alissa is varying as a function of time at a rate of 9 feet per second. Since the distance is a function of time, time is also a varying quantity.
Therefore, the only varying quantities are the distance between Alan and Alissa (ft/s) and the time (s).
