Question

Excluding stoppages, the speed of a bus is 54 kmph
and including stoppages, it is 45 kmph. For how
many minutes does the bus stop per hour?​

Answer 1

Answer:

As bus travels at 54 km/h excluding stoppages total distance covered is 54 kms in an hour. Now when the bus travels at 45 km/hr it takes 72 mins to travels same distance( Time = Dist/Speed.. t= (54*60)/45). So the excess 12 mins (72-60) is the time taken at stoppages.
