<PRE><B>Question 829558</B>
It takes 3 guys 8 hrs to finish a job
1 guy will take 3 times as long to do the same job, so
1 guy takes 24 hrs to finish the job
------------------------------
5 guys will take 1/5 of that time to do the same job, so
5 guys take {{{ 24/5 = 4.8 }}} hrs to finish the job
{{{ .8*60 = 48 }}} minutes, so
5 guys take 4 hrs and 48 min to finish the same job
