\n" ); document.write( "1/5 as many men will take 5 times as long
\n" ); document.write( "to do 1 wall
\n" ); document.write( "------------------
\n" ); document.write( "So, 2 men do 1 wall in $\"+5%2A24+=+120+\"$ hrs
\n" ); document.write( "------------------

\n" ); document.write( "3 times as many men, so
\n" ); document.write( "---------------------
\n" ); document.write( "6 men can complete 3 walls in 120 hrs,
