This is arranged as a uniform rates exercise, so you would assume (maybe incorrect in actual practice) that each person works according to his own rate.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "1 job is, install a floor.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Person_____________Rate, job per hour
\n" ); document.write( "Apprentice__________\"1%2F%28x%2B2%29\"
\n" ); document.write( "Experienced__________\"1%2Fx\"
\n" ); document.write( "Both together______\"1%2F%28x%2B2%29%2B1%2Fx\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The process of these workers is both together for 2 hours, the apprentice alone for 2 more hours; and the job is finished.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "RT=J for rate, time, job quantity. The sum of the work to be done will be 1 job.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"%281%2F%28x%2B2%29%2B1%2Fx%29%2A2%2B%281%2F%28x%2B2%29%292=1\".\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Your algebra or arithmetic skills should be enough that you can solve the equation for x, which is the time for the experienced carpenter to do 1 job alone. You can then find x+2.
