A person is to run a circular track with a radius of 93 meters. The person starts at a certain spot and runs 3 and 1/2 times around the track in a time of 227 seconds. Find the magnitude of average velocity for this trip (|vav|) and find the average speed for this trip. Then subtract the magnitude of the average velocity from the average speed (avg. speed - |vav|). Answer in m/s.
