Question

An 18 pound turkey cooks for 4.5 hours. How long will it take for a 12 pound turkey to cook?

Answer 1

3hrs.

Explanation:

18 pound turkey cooks for 4.5 hours

for one pound : 4.5/18=0.25 hr.

0.25 hr*60=15 minutes for one pound

12*15=180 min.=3 hrs

or 12*4.5/18= 3hrs

Answer 2

3 hours

Explanation:

We can solve using ratios

18 lbs 12 lbs

------------ = --------------

4.5 hrs x hours

Using cross products

18x = 12 * 4.5

18x = 54

Divide by 18

18x/18 = 54/18

x=3
