Jane can complete a sales in 5 hours, or 1/5th of a route per hour. Dave does 1/3rd a route an hour. So, together:
\n" ); document.write( "1/5+1/3=3+5/15=8/15 a route per hour.
\n" ); document.write( "1/(8/15)=15/8 hours as the amount of time they can finish a route working together. ☺☺☺☺
\n" ); document.write( "
\n" );
