John's rate of typing is $\"+1%2F5+\"$ papers/hours
\n" ); document.write( "Their rate together is $\"+1%2F2+\"$ papers/hours
\n" ); document.write( "Let $\"+t+\"$ = Jim's time to type 1 paper
\n" ); document.write( "---------------
\n" ); document.write( " $\"+1%2F5+%2B+1%2Ft+=+1%2F2+\"$
\n" ); document.write( "Multiply both sides by $\"+10t+\"$
\n" ); document.write( " $\"+2t+%2B+10+=+5t+\"$
\n" ); document.write( " $\"+3t+=+10+\"$
\n" ); document.write( " $\"+t+=+10%2F3+\"$ hrs
\n" ); document.write( " $\"+t+=+3+%2B+1%2F3+\"$ hrs
\n" ); document.write( " $\"+%281%2F3%29%2A60+=+20+\"$ min
\n" ); document.write( "Jim takes 3 hrs and 20 min to type the paper \n" ); document.write( "

\n" );
