Two trains T1 and T2 start simultaneously from two stations X and Y respectively towards each other. If
they are 85 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) 255km	B) 210km	C) 220km	D) 180km	E) 200km
In first 3 hours T1 travels R km and T2 travels S km.   255kmfter 6 hours they traveled R+S+85+ 85   2(R+S ) = R+S +170   R+S = 170   Hence distance between XY is R+S+ 85 = 170 +85=
