Luke paints a car in 6 hours while Daniel paints the same car in 3 hours. If they work together how long will it take them to paint the car?
\n" ); document.write( "--------------
\n" ); document.write( "Luke rate: 1/6 job/hr
\n" ); document.write( "Dan rate: 1/3 job/hr
\n" ); document.write( "---
\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 + 1/3 = 1/x
\n" ); document.write( "Multiply thru by 18x
\n" ); document.write( "--------------
\n" ); document.write( "3x + 6x = 18
\n" ); document.write( "9x = 18
\n" ); document.write( "x = 2 hrs (time to do the job together)
