How long do you cook a 1 7 lb roast?

I need more information to give you an accurate cooking time for a 1.7 lb roast! Here's what I need to know:

* What kind of roast is it? (Beef, pork, lamb, etc.)

* What cut of meat is it? (Chuck roast, prime rib, tenderloin, etc.)

* What cooking method are you using? (Oven, slow cooker, smoker, etc.)

* What is your desired internal temperature? (For example, 145°F for medium-rare beef)

Once you provide me with this information, I can give you a more accurate cooking time estimate.

In the meantime, you can use a meat thermometer to check the internal temperature of your roast and ensure it is cooked to your liking.
