Question
A train covers a distance of 77 km at the speed of 35
km/h the next 63 km distance covers with a speed of 42 km/h and last 24 km with the speed of 80 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 = 77 + 63 + 24 = 164 km Time1 = 77/35, Time2 = 63/42 & Time3 = 24/80 Total Time = 77/35 + 63/42 + 24/80 Therefore, Average Speed = 164/(77/35 + 63/42 + 24/80) = 41 km/hr
