Solve the following time-distance-velocity problem. Two railroad stations are 830 km apart. The first train leaves Station A at a speed of 80 km/h, bound for Station B. At the same time another train leaves Station A at a speed of 46 km/h, bound for Station B.
Assume there is a location (somewhere between A and B) at which the first train arrives exactly one hour earlier than the second train. How far is this point from Station A?
