Question 321796
<font face="Garamond" size="+2">


If it takes 3 cooks 2 hours, then each cook can prepare *[tex \Large \frac{1}{3}] of the meal in 2 hours, therefore each cook can prepare *[tex \Large \frac{1}{6}] of the meal in one hour.  So 5 cooks can prepare *[tex \Large \frac{5}{6}] of the meal in one hour, hence 5 cooks can prepare one meal in *[tex \Large \frac{6}{5}\ =\ 1.2] hours.
