Let distance = x
Total Distance = x + x = 2x
Time = x / 20 + x/ 30 = 5x / 60
Average Speed = Total Distance / Total Time
2x / (5x /60) = 2x * 60 / 5x = 24 km / hr
Total Distance = x + x = 2x
Time = x / 20 + x/ 30 = 5x / 60
Average Speed = Total Distance / Total Time
2x / (5x /60) = 2x * 60 / 5x = 24 km / hr
