Speeds given : without stoppage 54km/hr and with stoppage 45km/hr.
Vehicle has to cover same distance.
Let us assume it travels distance 270 kms (LCM of 54 and 45).
With 54 km/ hr, total 5 hrs are needed and with 45 km/hr, total 6 hrs are needed.
It means with stoppage it has to stop for I hr in 6 hrs.
So, within 1hr, it has to stop for 1/ 6 hr i.e. 10 minutes.

@Bharathi.
The main scenario is that, in one condition, the time taken by the bus for the stoppage in an hour, in another condition in that time the bus travelled some extra distance.
So, we have to calculate in how much time it travels the total extra distance i.e. 9 km and that is the time the bus spent on stoppages.
That's why we didn't consider 45.
