The average speed of the entire journey is 48.96km/h
In 20 min bus cover 12km
In 45 min bus cover 36km
In 1h bus cover 54km
So total distance is 102km
Total time is 125/60 hour
Now average speed will be (102×60)/125 = 48.96km/h
I hope this will help you

Where u got 12 km
bus speed is 36km/h, so if bus travel for 1h than it covers 36km. Now bus travel only for 20mins i.e. one third of 1h, so it covers one third of 36 i.e. 12km
