Since the train covers different distance with different speeds. So, Average speed = Total Distance/Total Time Total distance = 60 + 130 + 56 = 246 km Time1 = 60/30, Time2 = 130/50 & Time3 = 56/40 Total Time = 60/30 + 130/50 + 56/40 Therefore, Average Speed = 246/(60/30 + 130/50 + 56/40) = 41 km/hr
