Two trains T1 and T2 start simultaneously from two stations X and Y respectively towards each other. If
they are 60 km apart both 3 and 6 hours after start, then find the distance between the two stations. Choose the correct choice from the following:  A) 240 km  B) 200 km  C) 220km  D) 180km  E) 210km
In first 3 hours T1 travels R km and T2 travels S km.   After 6 hours they traveled R+S+60+ 60   2(R+S ) = R+S +120   R+S = 120   Hence distance between XY is R+S+ 60 = 120 +60 =200   Answer : 200 km
