if a 6-lb turkey takes 120 minutes to cook, how long would a 9-lb turkey take to cook?
Assuming that the cooking time is directly proportional to the weight of the turkey, we can set up a proportion:
6 lb turkey takes 120 minutes to cook
9 lb turkey would take x minutes to cook
(6 lb / 9 lb) = (120 min / x)
Cross multiplying:
6x = 9 * 120
6x = 1080
x = 1080 / 6
x = 180
Therefore, a 9-lb turkey would take 180 minutes to cook.
