Answer 2

Answer:

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

Explanation:

Gallons of water used by Chicago city in 1 day = $1.2\times 10^9 gal$

1 day = 24 hours

1 hour = 60 mins

1 min = 60 seconds

$1 day=24\times 60\times 60 min = 86,400 seconds$

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

= $1.2\times 10^9 gal$

Gallons of water used by Chicago city in 1 second:

$\frac{1.2\times 10^9 gal}{86,400}=13,888.88 gal$

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