Question
A car covers a certain distance at the speed of 30 km/h
and comes back at the speed of 20 km/h. What is the average speed of the car for the entire journey?Solution
Let the distance be x km. Time taken to go = x / 30 hours, Time taken to return = x / 20 hours. Total time taken = x / 30 + x / 20 = (2x + 3x) / 60 = 5x / 60 = x / 12 hours. Average speed = Total distance / Total time = (2x) / (x / 12) = 24 km/h.
