    Answer:

    7.2 h

    Step-by-step explanation:

    The time required is inversely proportional to the number of students.

    t = k/n or  

    tn = k

    Let t1  and n1 represent last year

    and t2 and n2 represent this year. Then

    t1n1 = t2n2

    Data:

    t1  = 9 h; n1 = 12 students

    t2 = ?;    n2 = 15 students

    Calculation:

    9 × 12 = t2 × 15

       108 = 15t2

         t2 = 108/15 = 7.2 h

    It will take the students 7.2 h to distribute the flyers.
