How long for 9 men to DO WHAT?
\n" ); document.write( "THE ONE JOB, which is to pick the two tones of oranges.
\n" ); document.write( "RT=J, relates rate, time, amount of jobs.
\n" ); document.write( "Here, we are focused on men and time for 1 job.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Assume each man works at the rate r and n number of men work at rate combined, nr.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Let t be the unknown time for the 9 men to do the same one job:
\n" ); document.write( "\"system%2815r%2A12=1%2C9r%2At=1%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Both equations are the quantity of the 1 job and are therefore equal.
\n" ); document.write( "\"15r%2A12=9r%2At\"
\n" ); document.write( "Notice factor r is on both members of this equation.
\n" ); document.write( "\"15%2A12=9%2At\"
\n" ); document.write( "\"%2815%2A12%29%2F%283%2A3%29=t\"
\n" ); document.write( "\"highlight%28t=20%29\"--------twenty days
\n" ); document.write( "
\n" );
