Lynn and &amp;nbsp;Farrah together work as productively as three instances of &amp;nbsp;Farrah,
and together they complete the job in &amp;nbsp;2 &amp;nbsp;hours.


It means that &amp;nbsp;Farrah can complete the job in &amp;nbsp;2*3 = 6 hours &amp;nbsp;working alone.


It implies that &amp;nbsp;Lynn can complete the job in &amp;nbsp;6/2 = 3 &amp;nbsp;hours working alone.
