    Okay, this one isn't too hard. They only ask you to draw it after an hour. So the one boat would simply have travelled 55 miles west, and the other 60 miles north.

    [See the image i attached]

    You probably want the distance between the boats.

    Lets name the hypotenuse S_{H}
    The course of the 55mph boat: S_{B55}
    The course of the 60mph boat: S_{B60}

    Let's use Pythagoras now.

    S_{H} ^ {2} = S_{B55} ^{2} + S_{B60} ^{2}
    S_{H} ^ {2} = (55)^{2} + (60)^{2}
    S_{H} ^ {2} = 6625

    Thus S_{H} = 81,394 miles
