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
