Let $\"+t+\"$ = time for then working together
\n" ); document.write( "Add their rates of working
\n" ); document.write( " $\"+1%2F30+%2B+1%2F20+=+1%2Ft+\"$
\n" ); document.write( "Multiply both sides by $\"+60t+\"$
\n" ); document.write( " $\"+2t+%2B+3t+=+60+\"$
\n" ); document.write( " $\"+5t+=+60+\"$
\n" ); document.write( " $\"+t+=+12+\"$ min
\n" ); document.write( "12 min working together\r
