Q8 of 32 Page 242

A School has 8 periods a day each of 45 minutes’ duration. How long would each period become, if the school has 6 periods a day? (assuming the number of school hours to be the same)

Given: Number of periods per day = 8

Duration of each period = 45 minutes


To find: Duration of each period if there are 6 periods per day


Formula:



Substituting x1 = 8, y1 = 45 x2 = 6 in the formula,



Gives y2 = 60


∴ Duration of each period will be 60 minutes if there are 6 periods.
