    Train A's speed every minute is 2.67Km and Train B's Speed per minute is 2 km
    If the trains travel at a constant velocity the distance between them decreases by 46 km every 10 minutes
    after 30 minutes the distance between them is less than 2 km

    If the supervisor is traveling at 14 km/h he will run 7 km in half an hour, so he will reach 6,3 km in less than 30 minutes. Therefore by the time he reaches the switch the trains will be 2 km apart
