Take it as ratio type 45 (9 * 5) : 54 (9 * 6).
Then convert it (54) to 60mins 50 : 60.
So 60 - 50 = 10 that's it.
Then convert it (54) to 60mins 50 : 60.
So 60 - 50 = 10 that's it.

1hr distance without stoppage = 54km,
1hr distance with stoppage = 45km,
=> distance difference = 9.
9/54*60=10.
1hr distance with stoppage = 45km,
=> distance difference = 9.
9/54*60=10.

Stoppage time = difference of speed/maximum speed.
= 54-45/54 * 60min,
= 9/54 * 60min,
= 1/6 * 60min.
= 10min.
= 54-45/54 * 60min,
= 9/54 * 60min,
= 1/6 * 60min.
= 10min.

I can't understand why we have taken 54km/hr for calculation. Why not 45km/hr? Anyone, please clarify it.

60 mins(1hr)--------------->54kms
???mins--------------------->9kms
solving we get the ans:-)
???mins--------------------->9kms

Fast speed-slow speed/Fast Speed = 54-45/54 = 1/6.
To convert into minutes =1/6 * 60 = 10.
To convert into minutes =1/6 * 60 = 10.

54km ------------- 60min
45km ------------- ?????.
45/54*60min = 50min.
60min - 50min = 10min.
45km ------------- ?????.
45/54*60min = 50min.
60min - 50min = 10min.

@Mr.Shaju
54 - 45 = 9 km is absolutely correct because we are calculating relative results.

Time taken to cover 9 km = 9 x 60 min = 10 min.

@Naren.
Because 54Kmph was the actual speed and 45Kmph was the speed after stoppage.
Because 54Kmph was the actual speed and 45Kmph was the speed after stoppage.
