If you run a complete loop around an outdoor track of length 400 m in 100 s, find your average velocity and average speed. Include units.

Average velocity = 0 m/s

Average speed = 4 m/s

Explanation:

Average velocity = Displacement / time

Average velocity = 0 / 100

Average velocity = 0 m/s

Displacement is distance on a particular direction.

So, if you started and came back to the same position, you haven't travelled in a particular direction.

Average speed = distance / time

Average speed = 400 / 100

Average speed = 4 m/s
