Excluding stoppages, the speed of a bus is 72 kmph and including stoppages, it is 60 kmph. For how many minutes does the bus stop per hour?

• Due to stoppages, it covers 12 km less.
  
  Time taken to cover 12 km = (12/72 x 60 ) min = 10 min.

• We can also solve it by formula, Time = difference in speed/speed of bus(excluding stoppage)
  Explanation,
  Time = (72-60)/72 = 1/6 hr = 10 mins.

• 10 min
  due to stoppage, 12 km less
  so, time taken to cover 12 km = 12*60/72 = 10 min
