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
