During a race on an oval track a car travels at an average speed of 200km/h. a) How far did it travel in 45.0mins? b) determine its average velocity at the end of its 3rd lap.
ok I worked out part a of the question and that is fine. But logically I can't figure out why the answer to the second part of the question would be 0. Can anyone explain why the average velocity at the end of the 3rd lap would be 0? thanks
