Answer 1

$\sf\huge{\underline{\underline\pink{AnsWeR}}}$

Given :-

Current no. of periods = 6

Duration of current periods = 60 min

Future no. of periods = 9

To Find :-

The duration of future periods.

Solution :-

We know that,

Current school hours (in total) can be found out by multiplying the number of current periods with the duration of each current periods.

Current school hours = (6 × 60) min

= 360 min

= 6 hours

The school has decided to keep the school hours unchanged.

Therefore new school hours = 360 min

&

New number of periods = 9

Duration of new periods = ${\dfrac{360}{9}}$

= 40 min

Therefore, each period would be of 40 minutes.

Answer 2

Answer:

6*60=360min

so it will be 6 hours

if nine periods will be there than 360 should be divided by 9 that is 40 minutes

so in the same school hours if there would be 9 periods Dan each one would be of 40 minutes
