2) 75 * 6 = 450 kilometers – the distance covered by the second train at a speed of 75 kilometers per hour in three six hours of its movement;
3) 300 + 450 = 750 kilometers – the distance traveled by two trains with speeds of 50 kilometers and 75 kilometers;
4) 275 + 750 = 1,025 kilometers – the distance, at this distance from each other these trains will be 6 hours after the start of movement.
