    44 hours

    Step-by-step explanation:

    Decreasing the people by a factor of 2 means we have 3 people

    The job takes 6 * 22 = 132 people hours

    When we decrease the people, it will take more hours

    132 people hours = 3 people * t hours

    Divide each side by 3

    132/3 = 3t/3

    44 = t

    It will take 44 hours
