Solve the following time-distance-velocity problem. Two railroad stations A and B are 700 km apart. Two trains leave station A at the same time - Train 1 at a speed of 70 km/h, bound for station B; and train 2 at a speed of 50 km/h, also bound for station B.
Assume there is a location (somewhere between A and B) at which the first train arrives exactly two hours earlier than the second train. How far is this point from station A?
