Question
A train covers a distance of 40 km at the speed of 30
km/h the next 50 km distance covers with a speed of 40 km/h and last 30 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 = 40 + 50 + 30 = 120 km Time1 = 40/30, Time2 = 50/40 & Time3 = 30/40 Total Time = 40/30 + 50/40 + 30/40 Therefore, Average Speed = 120/(40/30 + 50/40 + 30/40) = 36 km/hr
