  1. Answer:

    inverse proportion

    8 x 45 = 9 x y

    8 x 45 / 9 = y

    8 x 5 = y

    y = 40

    Each period will be of 40 minutes

  2. Step-by-step explanation:

    let the number of school hours be x

    duration of one period in a day = 45 min

    total number of periods before = 8

    x= 8*45

    x =360 min

    if periods will increase to 9 from 8 and the school hrs are same then the duration of 1 period = 360min /9 = 40min

    there fore the duration of one period will be 40 min
