Step-by-step explanation:
The number of hours it would take for a blood alcohol concentration (BAC) of 0.03% to reduce to 0.0% depends on a variety of factors, including the person's age, weight, gender, and overall health. In general, however, it is estimated that it takes about one hour for the body to metabolize one standard drink, which is equivalent to about 0.5 ounces of pure alcohol.
Assuming that a person has a BAC of 0.03% and that they have not consumed any additional alcohol during that time, it would take approximately 9 hours for their BAC to reduce to 0.0%. This is because 0.03% is equivalent to 0.5 ounces of alcohol, and it takes one hour to metabolize each 0.5 ounces of alcohol.
It is important to note, however, that this is only an approximate estimate, and the actual time it takes for a person's BAC to reduce to 0.0% can vary depending on the factors mentioned above. In some cases, it may take longer or shorter than 9 hours for a person's BAC to reduce to 0.0%. It is also important to remember that drinking alcohol can have serious health and safety risks, and that it is always best to drink responsibly and in moderation
