Let the distance between A and B = 'D'
Time taken while traveling from A to B with a speed of 30kmph = D/30
Time taken while traveling from B to A with a speed of 60kmph = D/60
.
Average speed = (Total Distance Traveled)/(Total time taken)
Average speed =
Average speed =
Average speed =
Average speed = 40kmph
