Average speed = distance covered divided by time. So simply determine how far 4 laps around the track is and divide by the time it takes. This will give you average speed in meters/minute. You may want to convert to meters per second.
Average velocity = distance between starting and ending points (which is actually a vector quantity) divided by time. Here's a hint - since the jogger goes around a track and completes 4 laps he ends up where he started, right? Can you take it from here? |
