\n" ); document.write( "Chad rate:: 1/2 job/hr
\n" ); document.write( "Cassie rate:: 1/3 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( "1/2 + 1/3 = 1/x
\n" ); document.write( "3x + 2x = 6
\n" ); document.write( "5x = 6
\n" ); document.write( "x = 1 1/5 hr = 1hr 12 min (time to do the job together)
