They paint at the same rate:
\n" ); document.write( "Call the rate of each ( 1 wall ) / ( t min ) = $\"+1%2Ft+\"$
\n" ); document.write( "Add their rates to get the rate working together
\n" ); document.write( " $\"+1%2Ft+%2B+1%2Ft+=+1%2F8+\"$
\n" ); document.write( " $\"+2%2Ft+=+1%2F8+\"$
\n" ); document.write( " $\"+t+=+16+\"$
\n" ); document.write( "Either one painting the wall alone will take 16 min
\n" ); document.write( " \n" ); document.write( "

\n" );
