Does 'last' mean when they are gone, or when you'd normally take another?
If you take one now, then one every 30min, they're gone in an hour... but your next pill would be due in another 30min.
The question should be at least closer to the subject, like "when will you run out of pills?"

You take one now and...
the other two last you forever.
1 hour 30 min, take one 30 minutes after the doc gives you the pills
1 hour
30 minutes, each pills effect lasts 30 min
or 2 hours and 30 min, stupid person thinks you can only take them on half hours
example: got pills at 2:00 took first one at 2:30 next at 3:30 and last at 4:30
