Final answer:
The BAC measurements for both the 200-pound man and his father, after drinking the same amount of alcohol, would likely be similar and above the legal limit of 0.08%, assuming average metabolic rates and no other health or tolerance differences.
Step-by-step explanation:
When comparing the BAC measurements of a 200-pound man and his father, also 200 pounds, after each drinking four 12 oz. beers with 5% ABV on an empty stomach over the course of one hour, several factors need to be considered. Since both individuals have the same weight and consumed the same amount of alcohol, the primary difference that could affect their BAC would be age and associated metabolic factors, as the rate at which alcohol is metabolized can vary. However, if no other differences are specified, assuming both individuals have average metabolism rates, we could expect their BAC levels to be similar initially. It is important to note that other factors such as health conditions and individual tolerance could further influence the BAC.
The BAC for both the man and his father are likely to exceed the legal intoxication limit of 0.08%. Taking into account the body's alcohol metabolism rate, it would take more than five hours for an individual who is legally intoxicated to achieve sobriety. The immediate effect of alcohol and associated BAC levels can vary widely between individuals. Therefore, it's difficult to state precisely what their BAC measurements would be without individual-specific data.
