Two trains T1 and T2 start simultaneously from two stations X and Y respectively towards each other. If
they are 40 km apart both 3 and 6 hours after start, then find the distance between the two stations. Choose the correct choice
A) 120km B) 150km C) 220km D) 180km E) 200km
In first 3 hours T1 travels R km and T2 travels S km.   120kmfter 6 hours they traveled R+S+40+ 40   2(R+S ) = R+S +80   R+S = 180   Hence distance between XY is R+S+ 40 = 40 +80 + + 40=
