    "current" problem/puzzle

    Well, I do know that at least Soroban likes this kind!

    Boat leaves point A, at constant speed b mph,
    against a current of speed c mph for 1st hour.
    The current's speed increases by 1 mph hourly.
    Like, boat nets (1st 3 hours): b-c, b-(c+1), b-(c+2)....

    At point B, after u hours, a hat falls out of
    the boat, and floats with the current towards A,
    and gets to A after travelling for v hours.

    Boat continues for another w hours to point C,
    where it turns around and heads towards A.
    YES, the boat reaches A at same time as the hat!

    Distance AB = d miles, distance BC = e miles.
    Be advised that e - d = 39 miles.
    Please note that w = 6 hours; you're welcome.

    b, c, d, e, u, v, w are all integers.
    Find b and v.
    I'm just an imagination of your figment !
