\n" ); document.write( "Barry DATA:
\n" ); document.write( "time = 3 hrs/job ; rate = 1/3 job/hr.
\n" ); document.write( "---------------------------
\n" ); document.write( "Sanchez DATA:
\n" ); document.write( "time = 5 hr/job ; rate= 1/5 job/hr
\n" ); document.write( "---------------------------
\n" ); document.write( "Together DATA:
\n" ); document.write( "time = x hr/job ; rate = 1/x job/hr.
\n" ); document.write( "---------------
\n" ); document.write( "EQUATION:
\n" ); document.write( "rate + rate = together rate
\n" ); document.write( "1/3 + 1/5 = 1/x
\n" ); document.write( "5x + 3x = 15
\n" ); document.write( "8x = 15
\n" ); document.write( "x = 15/8 hrs. (time to do the job together)
\n" ); document.write( "Comment: 15/8 hrs. = 1 hr. and 52 minutes and 50 seconds
