without stoppage ,the speed of a train is 54km/h and with stoppage,it is 45km/h.for how many minutes does the train stop per hour.

• Due to Stoppages it covers 9 km less.(54-45=9)
  time taken to cover 9 km=((9/54)*60)min=10 min

• THERE IS ONE FORMULA = a/a-b
  a=54,b=45
  54/54-45=1/6
  1/6*60=10
  so answer is 10

• use formula Smax/(Smax-Smin) = Number of stoppage/hr.
  60/no of stoppage = stoppage per Min

• a=54 and b=45 then change in spped/higher speed=time
  so 54-45/54
  =9/54
  =1/6 hours
  =1/6*60=10 minutes
  or 10*60= 600 seconds....ans

• 6 Min. 54-45=9km/hr
  9*5/18=2.5m/s
  9000/2.5=3600 sec..=60 min
