A 270 metres long train running at the speed of 120 kmph crosses another train running in opposite direction at the speed of 80 kmph in 9 seconds. What is the length of the other train?

Relative speed=s=(120+80)=200km/hr=[200*5/18]m/sec=500/9m/sec Length of 1st train=d1=270m Let the length of other train=x metres=d2 Total distance=d1+d2=d s=d/t t=9sec Then (270+x)/9=500/9 x=230m Ans is 230 metre

Relative speed = (120 + 80) km/hr =>200km/hr =(200)x5/18 =500/9 m/sec Let the length of the other train be x metres. Then, (x + 270)/9=500/9 x+270=500 x=230 meter so length of other train =230 meter
