    1+sqrt(2)

    I used s=vt, plugged in as much info possible rearranged it all to get the turning point multiplied by 2 and then plus 1

    My dad retired from the Navy. He used to say “fool me once, shame on you. Fool me twice and I ain’t going back to Bangkok!”

    No that can't be right, how far the messenger traveled depends on his speed relative to the rest of the group, which we don't know.

    Nope I'm wrong again because whatever the messengers speed, the back trip vs the front trip distances and times will be the same fraction, thus the same distance.
    At 100mph to the back the distance is lengthened to almost 1 mile, but then at 100mph to the front the distance is shortened.
    At 1mph the distance back is shortened to something like 1/4 mile but then at that slow speed the distance to the front is lengthened.

    Just don't know how to find that total distance.
    Probably under 2 miles.
