Question 560089: it takes 6hr for 5 cooks to prepare the food for a wedding dinner. How long will it take 9 cooks to prepare the dinner. What kind of variation applies to this situation. Solve the problem Found 2 solutions by josmiceli, Edwin McCravy:Answer by josmiceli(19441) (Show Source): You can put this solution on YOUR website! If 5 cooks take 6 hours, then
1 cook will take 5 times longer, so
1 cook takes 30 hrs to prepare the food
9 cooks will take 1/9 of that time , so
9 cooks will take hrs
9 cooks will take 3 1/3 hrs or 3 hrs and 20 min
This is an example of inverse variation because
( number of cooks ) = *( 1/ ( time to prepare dinner )

Inverse variation because the more the cooks the less the time.
(5 cooks)(6 hours) = (9 cooks)(x hours)
30 = 9x
= x
= x
3 hours and 20 minutes.
