6.Suppose that a cyclist began a 465 mile ride across a state at the western edge of the state , at the same time that a car traveling towards it leaves the eastern end of the state. If the bicycle and car met after 7.5 hr and the car traveled 37.4 faster than the bicycle. find the average of each.  the car average................ the bicycle average.............
