Answer #1

Part A

Calculate its average speed for the entire trip.

Average speed = Total Distance/Total time

ANSWER:

============================

Part B

Calculate its average velocity for the entire trip, using "away from the trainer" as the positive direction.

Average velocity= Total Displacement/Total time

In the case of displacement consider the direction.
