Question
A train travels from Station A to Station B at a speed
of 60 km/h and returns from Station B to Station A at a speed of 40 km/h. If the distance between the two stations is 120 km, find the average speed of the train for the entire journey.Solution
Let the distance between the two stations be 120 km. Time taken to travel from A to B = 120/60 = 2 hours. Time taken to travel from B to A = 120/40 = 3 hours. Total time taken for the round trip = 2 + 3 = 5 hours. Total distance traveled = 120 + 120 = 240 km. Average speed = 240/5 = 48 km/h.
