\n" ); document.write( "Let x = amount of time it takes both working together to deliver all the papers\r
\n" ); document.write( "\n" ); document.write( "Candy delivers papers at the rate of 1/30 of the route per minute
\n" ); document.write( "Tim delivers papers at the rate of 1/90 of the route per min\r
\n" ); document.write( "\n" ); document.write( "Together, they deliver papers at the rate of 1/30 + 1/90=3/90 + 1/90=4/90 of the route per min. So, our equation to solve is:\r
\n" ); document.write( "\n" ); document.write( "(4/90)*x=1 (one paper route, that is, all the papers) multiply each by 90\r
\n" ); document.write( "\n" ); document.write( "4x=90 divide each side by 4
\n" ); document.write( "x=22.5 minutes-------------amount of time it takes both to deliver all the papers working together\r
\n" ); document.write( "\n" ); document.write( "CK
\n" ); document.write( " together they deliver at the rate of 1/22.5 of the route per min\r
\n" ); document.write( "\n" ); document.write( "4/90=1/22.5\r
\n" ); document.write( "
