Let x minutes be the duration of period when the school has 6 periods a day.
Then Number of periods = 8
Duration of periods (in minutes) = 45x
Clearly, more the periods, less will be the duration of the period.
So, it is a case of inverse proportion.
Hence, the duration of period is 60 minutes.
60 minutes
Step-by-step explanation:
Number of Periods at day = 8
Duration of periods= 45 minutes
total school hours =( 8*45)/60 hr
360/60= 6hrs
Assuming 6 period a day,
Total school minutes = 360
Duration of periods = 360/6
= 60 minutes
So, assuming 6 period a day duration of period will be 60 minutes.
