Answer 1

Answer:

60 minutes

Step-by-step explanation:

let the time taken each period be X

9×40=360

360=6×X

X=360÷6

X=60

Answer 2

Answer:

total school hours = 9 periods ×40 minutes

= 360 minutes

Now, school is having only 6 periods a day

therefore

1 period would be 360(total school hours)÷6(number of periods) minutes long

360/6 = 60 minutes

thereforr as we know that 60min =1 hour

a period is 1 hour or 60 minutes long
