Experts estimate that when the levees around New Orleans broke in the aftermath of Hurricane Katrina in 2005, water flowed into the city at a peak rate of 9 billion gallons per day. There are 7.5 gallons in one cubic foot. Find the flow rate in units of cubic feet per second (cfs). Compare this flow rate to the average flow rate of the Colorado River in the Grand Canyon, which is 30,000 cfs.2.
