If you have had three beers in the past hour, how long will it take for all the alcohol to leave your blood stream?

  1. one hour

  2. two hours

  3. three hours

  4. None of the above

The correct answer is: three hours

When alcohol enters your bloodstream, your liver processes it at a rate of about one standard drink per hour. Since you have consumed three beers in the past hour, it will take a minimum of three hours for all the alcohol to leave your bloodstream. This is why the correct answer is three hours (option C). The other options are incorrect because alcohol does not leave the bloodstream at a rate of one standard drink per hour when more than one drink has been consumed.
