then what is the average speed over the whole journey ?
Between the two stations, a train accelerates from rest uniformly at first, then moves with constant velocity and finally retards uniformly to come to rest. If the ratio of the time taken is 1 : 8 : 1 and the maximum speed attained be 60 km/h, then what is the average speed over the whole journey ?
