Question
A train covers a distance of 60 km at the speed of 30
km/h the next 130 km distance covers with a speed of 50 km/h and last 56 km with the speed of 40 km/h find the average speed of the train?Solution
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
