Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

You take the first pill immediately at hour zero, the second pill half an hour later, and the third and final pill half an hour after that, making the total elapsed time exactly one hour. Counting incorrectly often leads to 1.5 hours by adding half an hour for every pill rather than counting intervals.
