The time taken by the bus for i k.m is 60/54=1.11 min
so if the bus travels 9 k.m less due to stoppage
then the ans will be =1.11*9=10 min.
so if the bus travels 9 k.m less due to stoppage
then the ans will be =1.11*9=10 min.

I still didn't understand.
If 54km - 45 km = 9 km. That is speed reduces by 9 km/hr.
So 60/9 = 20/3 per min...now how do i proceed next?

We have taken 54 because if we take 45, this is the speed of bus with the stoppage, it has already taken the stop that's why 54 is taken.

the formula of stoppage time per hour = difference between their average speed/Speed without stoppage
Hence ,(54-45)/54*60 = 10 minute.
Hence ,(54-45)/54*60 = 10 minute.

Answer is coming 12 min,
s = d/t.
54 = d because t = 1hr given -------- 1,
s = d/t.
45 = 54/(t+1) ------- 2.
By solving we get 12.
s = d/t.
54 = d because t = 1hr given -------- 1,
s = d/t.
45 = 54/(t+1) ------- 2.
By solving we get 12.

@Nen.
60 mins(1hr) ------> 54kms,
? mins -------------> 9kms.
1 * 9/54 = 1/6 = 10mins.
By solving this we get the answer.
60 mins(1hr) ------> 54kms,
? mins -------------> 9kms.
1 * 9/54 = 1/6 = 10mins.

54 kms in 1 hour..but in 1 hour it travelled only 45 kms..9 kms less..
1 hour-54 kms
??? - 9kms
1x9/54 = 1/6 hour = 10 minutes
1 hour-54 kms
??? - 9kms
1x9/54 = 1/6 hour = 10 minutes

For 60 min......54 kmph so.
For ? min.......45 kmph.
= 45*60/54 = 50 mins it means 10 mins less so it has stopped for 10 mins.
For ? min.......45 kmph.
= 45*60/54 = 50 mins it means 10 mins less so it has stopped for 10 mins.

Travelling difference = 9 km/hr.
Travels 54 km taking 60 mins.
Hence, travels 9 km taking 10 mins.
So, the answer is 10 mins.
Travels 54 km taking 60 mins.
Hence, travels 9 km taking 10 mins.
So, the answer is 10 mins.

2 speeds difference is 9 km,
So we should calculate the time taken to cover 9 km.
So, 9/54*60 =?
Then the answer is 10 minutes.
