Joes team can completely manicure the lawn at Detroit Park in 12 hours. When Sally's team was brought on to help, the job was done in about 5 1/2 hours. How long does it takes Sally's team to completely manicure the lawn when they are working alone?
\n" ); document.write( "----
\n" ); document.write( "Joe's rate: 1/12 job/hr
\n" ); document.write( "Together rate: 1/(11/2) = 2/11 job/hr
\n" ); document.write( "Sally rate = 1/x job/hr
\n" ); document.write( "-----
\n" ); document.write( "Equation:
\n" ); document.write( "rate + rate = together rate
\n" ); document.write( "1/12 + 1/x = 2/11
\n" ); document.write( "---
\n" ); document.write( "Multiply thru by 132x to get:
\n" ); document.write( "11x + 132 = 24x
\n" ); document.write( "13x = 132
\n" ); document.write( "x = 10 hrs 9 minutes (time for Sally's team to do the job alone)
\n" ); document.write( "==========
