The cell membrane is semi-permeable, kind of like a filter to let some molecules in and keep larger molecules out
        
                    
             
        
        
        
so you’d need to find the amount of gallons your family uses in 11 minutes and subtract 73000 from that number
i used the same formula, came up with 80300 gallons a year, and subtracted 73000 from it to get
7300 gallons are saved by reducing showering time by one minute
