An experienced employee can enter tax data into a computer twice as fast as a new employee. Working together, it takes the employee 2 hr. How long would it take the experienced employee working alone?
\n" ); document.write( "-----------------------------------
\n" ); document.write( "Old worker DATA:
\n" ); document.write( "time = x hr/job ; rate = 1/x job/hr
\n" ); document.write( "----------------------
\n" ); document.write( "New worker DATA:
\n" ); document.write( "time = 2x hr/job ; rate = 1/(2x) job/hr
\n" ); document.write( "----------------------
\n" ); document.write( "Together DATA:
\n" ); document.write( "time = 2 hr/job ; rate = 1/2 job/hr
\n" ); document.write( "-----------------------------
\n" ); document.write( "Equation:
\n" ); document.write( "rate + rate = together rate
\n" ); document.write( "1/x + 1/(2x) = 1/2
\n" ); document.write( "Multiply thru by 2x to get:
\n" ); document.write( "2 + 1 = x
\n" ); document.write( "x = 3 hrs (time for experienced worker to do the job)
