Question

Question 10 options: It takes 15 minutes to cook 1 pound of turkey. If you have a 21 pound turkey, how many hours/minutes will it take to cook the bird? Hour(s), and minutes

Answer 1

Answer:

$5\ hours\ and\ 15\ minutes$, or $5.25\ hours$, or $315\ minutes$

Step-by-step explanation:

You know that 1 pound of turkey can be cooked in 15 minutes.

Then, in order to find the time it takes to cook 21 pounds of turkey, you can set up the following proportion:

$\frac{15\ minutes}{1\ pound}=\frac{x}{21\ pounds}$

Now you must solve for "x":

$(21\ pounds)(\frac{15\ minutes}{1\ pound})=x\\\\x=315\ minutes$

Since $1\ hours=60\ minutes$, you can express the time as:

$(315\ minutes)(\frac{1\ hour}{60\ minutes})=5.25\ hours$ or  $5\ hours\ and\ 15\ minutes$
