Question

Pls just give answer

Answer 1

`(1)/(21)`

Explanation:

between 10 pm & 7.20 am = 10 pm to 12 am + 12 am to 7.20 am

= 2 hrs + (7 hrs + 20 minutes)

= 9 hrs + 20 minutes

=
`9\ hrs +(20)/(60) \ hrs`

=
`9(1)/(3) \ hrs`

=
`(28)/(3) \ hrs`

`rate=(total\ of\ water)/(total\ of\ time)`

`=((4)/(9) )/((28)/(3) )`

`=(4)/(9) /(28)/(3)`

`=(4)/(9) *(3)/(28)`

`=(1)/(21) \ inch\ per\ hr`
