(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

PARAG KAMRA  (11 years ago)

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.
