a train 108 long moving at a speed 50kmph crossed a 112 meter long train coming from opposite direction in 6 sec what is the speed of second train?

• (220*18)/5(x+50)=6
  250 + 5x = 660
  
  => x = 82 km/hr.

• Let the speed of 2nd train is xkm/h
  as both trains are moving towards each other relative speed of the 1st train is (50+x)kmph
  distance covered to cross 112m long train is (112+108)=220m=0.22km
  so 0.22/(50+x)=6/3600(hour)
  solving this we get speed of 2nd train as 82kmph

• let us suppose speed of second train is x
  Distance covered = (108 + 112) = 220 m.
  speed=(x+50)*5/18
  (220*18)/(x+50)=6
  => 250 + 5x = 660
  
  => x = 82 km/hr.
