A runner travels 2.5 laps around a circular track in a time of 75 sec. The diameter of the track is 50 m and its circumference is 120 m. Find (a) the average speed of the runner and (b) the magnitude of the runner's average velocity. Average speed depends on the total distance traveled, whereas average velocity depends on the displacement at the end of the particular journey.
