You can put this solution on YOUR website!
r = houses/(people*time)
\n" ); document.write( "r = 20/(10*30) = 10/(5*time)
\n" ); document.write( "20/(10*30) = 10/(5*time)
\n" ); document.write( "5*20/(10*30)/10 = 1/time
\n" ); document.write( "time = 1/( 5*20/(10*30)/10 )
\n" ); document.write( "---
