A train has speed of 54km in first hr .then train stoppages is there and then train goes with a speed of 45 km /hr in next 1 hour ,then how much time the train stops in whole journey ?

• let the train cover distance in ihr or 60 min =54
  now when there r stopsge its speed =45 bt the distance remain change and the time change in inversely oropotio
  now54-45=9
  so with stopage it takes 9 min more or say without stopage it cover 9 km more the distance it cover with stopage
  so 9/54)*60 we get the ans as 10

• ans=12mint
  first hr=54km
  2nd avg speed=45km/hr
  distance coverd in first hr=54
  distance in 2nd hr=45
  lagging 54-45=9km
  so in coving 9 km train takes 1.2 hr with speed of 54km/hr
  means 0.2 hr more
  ie,0.2x60=12
