it takes a 40 lb turkey two hours to cook. Tom baked his own turkey that was 1/5 the size of a 40 lb turkey. How long will it take for Toms turkey to bake ?

This is a faulty problem.
First, I've never seen a 40lb. turkey.
Second, it takes several hours to cook a 20lb. turkey.
Third, an 8lb turkey would take much longer than 15 minutes! 
this problem was written by someone who cooks their thanksgiving dinner in the microwave.

its a question in a math book. i tried to figure out the answer and got 15 minutes. hope its right ?

Using the math the book's author expects, you're right. But I wouldn't have the nerve to turn in such a ridiculous answer.

40lbs=120mins;...8lbs=120mins/5=24mins....it takes 24mins to cook 8lbs of turkey.
