Two trains T1 and T2 start simultaneously from two stations X and Y respectively towards each other. If
they are 80 km apart both 3 and 6 hours after start, then find the distance between the two stations. Choose the correct choice from the following options:
A) 240 km B) 230 km C) 220km D) 180km E) 200km
In first 3 hours T1 travels R km and T2 travels S km.   240 kmfter 6 hours they traveled R+S+80+ 80   2(R+S ) = R+S +160   R+S = 160   Hence distance between XY is R+S+ 80 = 160 +80=
