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

I have the same doubt that what rahul having..if we subtracting two speeds ,then we will get difference in speed na? how we got the distance 9 km?

Rahul....Question is right only...Actually without stoppages it cover 54 but with stoppages it cover only 45...so only we need to subtract...to get the speed without stoppages..so 54-45=9..Then we having speed with stoppages ..so only considering 9\54 then we need to get min so mul by 60..now got?
