First find the one-student work rate. The 1 job is, \"clean up the classroom\".\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "six students needing 20 minutes means that 1 student needs \"6%2A20=120\" minutes if working alone. This rate is \"1%2F120\" job/minute.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The uniform rate equation for n number of students is \"highlight%28n%281%2F120%29t=1%29\" for doing ONE job.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"n=6%2B3=highlight_green%289%29\" students to do the job.
\n" ); document.write( "\"t=120%2Fn\"
\n" ); document.write( "\"t=120%2F9\"
\n" ); document.write( "\"highlight%28t=13%261%2F3%29\" minutes\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Thirteen minutes 20 seconds
\n" ); document.write( "
\n" );
