\n" ); document.write( "Janice DATA:
\n" ); document.write( "time = 2 hrs/job ; rate = 1/2 job/hr
\n" ); document.write( "----

\n" ); document.write( "time = 2 hrs/job ; rate = 1/2 job/hr
\n" ); document.write( "---
\n" ); document.write( "Together DATA:
\n" ); document.write( "time = x hrs/job ; rate = 1/x job/hr
\n" ); document.write( "-----
\n" ); document.write( "Equation:
\n" ); document.write( "rate + rate = together rate
\n" ); document.write( "1/2 + 1/2 = 1/x
\n" ); document.write( "1/x = 1
\n" ); document.write( "x = 1 hr (time for them to do the job together)
