\n" ); document.write( "Since the rate of pipe A is twice that of pipe B, when the two work together pipe A does 2/3 of the job and pipe B does 1/3 of the job.

\n" ); document.write( "It takes the two together 6 hours to fill the tank.

\n" ); document.write( "So in those 6 hours that it takes the two pipes together to fill the tank, pipe B fills 1/3 of the tank.

\n" ); document.write( "And if pipe B fills 1/3 of the tank in 6 hours, it will take it 18 hours to fill the whole tank alone.
