Let n be the amount of time it takes for the assistant working alone. Then:
\n" ); document.write( "1/45+1/n=1/40
\n" ); document.write( "8n+360=9n
\n" ); document.write( "n=360
\n" ); document.write( "It would take the assistant 360 minutes, or 6 hours, to do the route alone. ☺☺☺☺
\n" ); document.write( "
\n" );
