The average speed for his whole trip is the average of his both forward and returning trip. Therefore it become average of 20 and 80 kmph.
Therefore the average speed is 50kmph.
*Average speed is the total distance traveled upon total time taken.
Let the first average distance be 20 km and second be 80km. Total time taken would be 2 hours.
Therefore we get 50kmph as average speed.
Therefore the average speed is 50kmph.
