Question

Alan and Alissa and attemping to find each other in a crowded mall. They finally spot each other near the food court, at which point they are 140 feet apart. They begin walking towards each other. Alan travel at a constant rate of 5 feet per second and Alissa travels at a constant rate of 4 feet per second.What quantities are varying in this context ?

Answer 1

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).
