a runner travels 1.5 laps around a circular track in a time of 50 s . The diameter of the track is 40 m and its circumference is 126 m. Find (a) the average speed of the runner and (b) the magnitude of the runner’s average velocity. Be careful here ; average speed depends on the total distance traveled, whereas average velocity depends on the displacement at the end particular journey
