Question

A school has 8 periods at day each of 45 minutes duration. How long would each period be ? The school has 6 periods a day? (assuming the number of school hours to be the same)​

Answer 1

The duration of each period would be 60 minutes.

Justification:

Let the duration of each period be x.

Here the number of periods and the duration of periods are in inverse proportion.

∴ 8/6 = x/45

6x = 360

x = 360/6

x = 60.

Answer:

The school has 6 periods a day needs 1 hour for each.

Step-by-step explanation:

8 period =45×8=360 minute

6 perod =360/6=60minute
