State the importance of considering speed when calculating total distance over the same time frame.

Here is the answer to question (c).

c) State the importance of considering speed when calculating total distance over the same time frame.
Speed is crucial because distance is directly proportional to speed when the time frame is constant. If an object's speed changes, the distance it covers within that same time frame will also change. Therefore, to accurately calculate the total distance traveled, one must know the specific speed(s) at which the movement occurred.
