    tl;dr

    draw a graph with time across the bottom and time on the side

    plot the progress on the way up , and then on the way down

    whatever way you do it the the lines must cross ( unlike ghostbusters )

    the point at which the lines cross depends on the speed you do different parts of the journey at


    but you only need four colours to do a map , and that includes the blue for all interconnected seas, rivers and lakes, - so you actually only need 3 colours for the countries / counties

    One day,starting at Eight o clock,you go up a hill ,sometimes running and sometimes walking and it takes 12 hours, you spend the night on the hill top.
    Next day,starting at Eight o clock, you start back down, sometimes running ,some times walking and it takes 12 hour again
    Is there a place where you were at the the same place at the same time on both days?

    At the bottom?

    If you colour water connected to the oceans as blue, then you only need three colours for the rest.
