So, her it goes
In first journey distance covered is 40
and time is
=d/sp = 40/80 = 1/2 hour or 30 minutes
2nd journey distance is 40km and time is 1 hour
So average speed = total distance/total time
so 80km is total distance and 1.5 hour total time
average speed = 80km/1.5 h = 53.33km/h
So,average speed us 53.33 km/h
Hope it will not help...........just kidding
