A 300 meter long train running at the speed of 120 kmph crosses another train running in the opposite direction at the speed of 80 kmph in 9 seconds.What is the lenght of other train. Choose the correct option
A) 210m  B) 220m  C) 230m  D) 240m  E) 200m
Relative speeds=(120+80)km/hr   =200km/hr=(200*5/18)m/s=(500/9)m/s   let length of train be xm   x+300/9=500/9   x=200   Ans is 200m   ANSW200mR:200m
