Find the one-cook rate. Seven cooks do the job in 2 hours, so only one cook needs 7 times longer; or \"2%2A7=14\" hours.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "r*t=j for rate, time, job.
\n" ); document.write( "One cook, 1/14 jobs per hour.
\n" ); document.write( "Three cooks, 3/14 jobs per hour.
\n" ); document.write( "-
\n" ); document.write( "Let t = time in hours to do this one job.
\n" ); document.write( "\"highlight_green%28%283%2F14%29t=1%29\"
\n" ); document.write( "
