Answer»

Answer:

13888.8888... ≅ 13,888.89 Gallons / Second

Step-by-step EXPLANATION:

<klux>1</klux>.2 * 10^9 = 1,200,000,000 (8 Zeros)

1 Day = 24 HOURS

24 Hours = 60 minutes

1 Minute = 60 seconds

60 x 60 = 3600 (The number of seconds in an HOUR)

3600 x 24 = 86,400 (The number of seconds in a 24 hour period or ONE day)

\frac{1,200,000,000}{86,400} = 13,888.88...
