His regular speed reduce 54k/h to 45k/h.
So we have to find out the missing time from the regular speed.
The difference of the distance is 9kmh.
So missing time = (1* 9/54) * 60min.
= 10min.

It's very simple.
54 - 45\54 * 60 = 10 min.
54 - 45\54 * 60 = 10 min.

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.
