    Answer:
    10 Classroom
    Step-by-step explanation:
    Since,
    Custodian clean 2 classrooms in 15 minutes
    Then ,
    Let’s see how many minutes does it takes for a custodian to clean for 1 classroom
    To Find that we have to divide the given minutes by the given classroom.
    15/2 = 7.5
    Hence, in 7.5 minutes a custodian clean 1 classroom
    Therefore:
    Classroom to minutes:
    1 = 7.5
    2 = 15
    3 = 22.5
    4 = 30
    5 = 37.5
    6 = 45
    7 = 52.5
    8 = 60
    9 = 67.5
    10 = 75
    11 = 82.5
    Hence, we round to the nearest number:
    which is 10 classroom in 75 minutes.
    For this reason, the answer is about 10 classroom
