Question

a school has 8 periods a day of 45 minute is if the School decided to helpline periods are day without increasing the number of school Har how long is period be​

Answer 1

Step-by-step explanation:

Let x minutes be the duration of period when the school has 9 periods a day.

Then

Number of periods = 8

Duration of periods (in minutes) =45min

Clearly, more the periods, less will be the duration of the period.

So, it is a case of inverse proportion.

8×45 9×x

⇒x= 8×45 upon 9 = 40

Hence, the duration of period is 40 minutes.
