    In order to answer this questions, let's suppose,

    The time it takes for Sam and Joe to meet in hours = t

    Joe's speed = 1.5miles/hour

    Sam's speed = 2 miles/hour

    Distance between Joe and Sam = 7 miles

    When they meet Joe covers a distance of J miles and Sam covers S miles

    Now,

    J+S=7

    J=1.5 miles/hour * t

    S = 2 miles/hour * t

    1.5t + 2t = 7

    3.5 t = 7

    t=2 hours

    It will take 2 hours for Sam and Joe to meet
