\n" ); document.write( "-------
\n" ); document.write( "zoe rate:: 1/4 job/hr
\n" ); document.write( "---
\n" ); document.write( "stan 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( "1/4 + 1/3 = 1/x
\n" ); document.write( "3x + 4x = 4*3
\n" ); document.write( "7x = 12
\n" ); document.write( "x = 12/7 = 1.71 hrs = 1hr 0.71*60 min = 1hr 42sec (time to do the job together)
