Average speed =
Average velocity =
Explanation:
Distance traveled North:
Distance traveled South:
Total distance traveled:
Total time:
Average speed =
If we take North as the positive direction, total displacement:
This is the distance of the object from its starting point, and includes a direction.
Average velocity =
