To estimate the cooking time for a five-pound roast based on a four-pound roast taking 150 minutes, you can use a simple ratio. If 4 pounds takes 150 minutes, then 5 pounds would take approximately 187.5 minutes (150 minutes multiplied by 5/4). Therefore, you should cook the five-pound roast for about 188 minutes, or 3 hours and 8 minutes. Keep in mind that cooking times can vary based on the type of roast and cooking method.
