    5, 10 and 16

    Explanation:

    The sum of their ages is √961 = 31

    If Joe is x years old, the equation that follows is:

    x + (x+5) + (x+5+6) = 31

    This simplifies to

    3x = 31 - 11 - 5 = 15

    so x=5

    From that you can find

    Joe = x = 5

    Kate = x+5 = 10

    Jody = x+5+6 = 16
