Jack usually mows his lawns in 6 hours. Marilyn can mow the same yard in 5 hours. How much time would it take for them to mow the lawn together?
\n" ); document.write( "---
\n" ); document.write( "Jack's rate: 1/6 job/hr
\n" ); document.write( "Marilyn rate: 1/5 job/hr
\n" ); document.write( "Together rate: 1/x job/hr
\n" ); document.write( "-----
\n" ); document.write( "Equation:
\n" ); document.write( "rate + rate = together rate
\n" ); document.write( "1/6 + 1/5 = 1/x
\n" ); document.write( "----
\n" ); document.write( "Multiply thru by 30x to get:
\n" ); document.write( "5x + 6x = 30
\n" ); document.write( "11x = 30
\n" ); document.write( "x = 30/11 = 2 8/11 hrs (time to do the job together)
