This is a faulty problem.
First, I've never seen a 40-lb. turkey.
Second, it takes several hours to cook a 20-lb. turkey.
Third, an 8-lb turkey would take much longer than 15 minutes!

Weight of Tom's turkey = (1/5) * 40 lb
= 8 lb
Now that we know Tom's turkey weighs 8 lb, we can use the cooking time for the 40 lb turkey as a reference to estimate the cooking time for Tom's turkey. Since Tom's turkey is smaller, it will generally require less time to cook.
However, it's important to note that cooking times for different-sized turkeys can vary. Factors such as the oven temperature, cooking method, stuffing, and other variables can affect the cooking time. Therefore, it's always a good idea to use a meat thermometer to check for doneness.
To provide a rough estimate, let's assume that the cooking time is somewhat proportional to the weight. We can set up a proportion to find the cooking time for Tom's turkey:
40 lb turkey => 2 hours
8 lb turkey => x hours
Proportion: 40 lb / 2 hours = 8 lb / x hours
Now, we can solve for x (the time for Tom's turkey to bake):
40 lb * x hours = 8 lb * 2 hours
40x = 16
x = 16 / 40
x = 0.4 hours
Therefore, it will take approximately 0.4 hours to bake Tom's turkey, or equivalently, 24 minutes.
