Answer 1

13888.8888889 i think?

Answer 2

13,888.88 gallons per second must be pumped from the adjacent Lake Michigan every second to supply the city.

Step-by-step explanation:

Gallons of water used by Chicago city in 1 day =
`1.2* 10^9 gal`

1 day = 24 hours

1 hour = 60 mins

1 min = 60 seconds

`1 day=24* 60* 60 min = 86,400 seconds`

Gallons of water used by Chicago city in 86,400 seconds :

=
`1.2* 10^9 gal`

Gallons of water used by Chicago city in 1 second:

`(1.2* 10^9 gal)/(86,400)=13,888.88 gal`

13,888.88 gallons per second must be pumped from the adjacent Lake Michigan every second to supply the city.
