    18

    More hours => more burgers.
    More boys => more burgers.

    The time become twice (3 hours / 1.5 hours).
    Boys become six times (9 / 1.5).

    Number of burgers = 2 * 6 * Original(1.5)
    = 18

    While anikam’s answer is mathematically correct, he failed to take into account that after one and a half burgers, the boys were full and ate no more in the next one and a half hours.  Thus, the answer for nine boys is six.
