Add their rates of mowing to get rate working together
\n" ); document.write( "John's rate: ( 1 lawn ) / ( 9 hrs )
\n" ); document.write( "Rate working together: ( 1 lawn ) / ( 4.6 hrs )
\n" ); document.write( "Let $\"+t+\"$ = Tim's time in hrs to mow lawn by himself
\n" ); document.write( "Tim's rate: ( 1 lawn ) / ( t hrs )
\n" ); document.write( "-------------------------
\n" ); document.write( " $\"+1%2F9+%2B+1%2Ft+=+1%2F4.6+\"$
\n" ); document.write( "Multiply both sides by $\"+4.6%2A9%2At+\"$
\n" ); document.write( " $\"+4.6t+%2B+4.6%2A9+=+9t+\"$
\n" ); document.write( " $\"+9t+-+4.6t+=+4.6%2A9+\"$
\n" ); document.write( " $\"+4.4t+=+4.6%2A9+\"$
\n" ); document.write( " $\"+t+=+%28+4.6%2A9+%29+%2F+4.4+\"$ hrs
\n" ); document.write( "Use calculator to solve \n" ); document.write( "
