Chicago uses 1.2(10^9) gallons of water per day. How many gallons per second must be pumped from the lake every second to supply the city?

1 day=24hours
1 hour=60 minutes
1 minute=60 seconds

Divide by all this numbers
1.2(10^9)/24/60/60=. And that should be your total...

OK.  1.2x10^9 gal/day  is a lot of water.  So you need to calculate how many seconds there are in a day....well 60s/m*60m/hr*24hr/day.  = 86400 sec/day.  Now divide that number into the given to get
1.3889 x10^4 gal/sec approximately.
