Excluding Stoppages ,the speed of the bus is 54 KMPH and including stoppages 45KMPH ,for how many minutes does bus stop per hour?

• Original speed of the bus = 54km/h
  Difference in speed is = 54 - 45 = 9km/h
  
  So the bus covered 9km less due to stoppages...
  Time taken to cover 9km is = 9/54 = 1/6 hrs => 10mins
  The bus stops 10 mins/hr
  
  Ans : 10 mins/hr

• 10 mins difference in speed =9kmph
  speed=54kmph=15 m/s
  sp time stopped=9000m/15m=600s=10 mins
