the distance between two stations is 300km. two trains start simultaneously from these stations and move towards each other ,the speed of one them is 7k/hr more than the other . if the distance between them after 2hours of their start is 34km ,find the speed of each train ????

Train #1 = X km/h.
Train #2 = (X+7) km/h.
d1 + d2 = 30034.
2x + 2(x+7) = 266
4x + 14 = 266
4x = 26614 = 252
X = 63 km/h.
X+7 = 63+7 = 70 km/h.
