Question

If a doctor gives you 3 pills and tells you to take one pill every half hour, how long would it take before all the pills had been taken?

Answer 1

1 pill per 30 mins
3 total pills
30 mins times 3 pills = 1 hour and 30 mins

It would take one hour and 30 minitutes before all the pills would have been taken.

Answer 2

One hour. You take the first pill, then wait a half hour and take the second pill, then at the hour mark you take the third and last pill.
