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

• Speed excluding stoppages = 54 kmph
  So in 1 hr, it ll cover 54 km
  
  Speed including stoppages = 45 kmph
  So In 1 hr, it ll cover 45 km
  
  Difference due to stoppages = 54 - 45 = 9 km
  Time taken to cover 9km = 9/54 = 1/6 hrs => 1/6 * 60 mins => 10 mins
  
  Ans : 10 mins

• Due to stoppages, it covers 9 km less.
  
  Time taken to cover 9 km = (9/54) hour
  = (1/6)*60 minutes
  = 10 minutes
