If a doctor prescribes three pills and one is to be taken every half hour, the pills will last 60 minutes. For example, if the first pill is taken at 12:00, the second pill will be taken at 12:30 and the third at 1:00 for a total of 60 minutes.
You are told to take a pill every hour. You have 3 pills. How long before they are all gone?
2 Hours
One Hour.
You would take the initial pill. That starts the clock. Thirty minutes later you would take the second pill then, after another 30 minutes you would take the third pill. They would be gone in 1 hour.
It is "An" hour, not a hour. The "an" comes before every vowel sound, not every vowel.
30 minutes
An hour. For example: If you take one at 9:00, then 9:30, then 10:00 - that's one hour.
2 houers
60 minutes. take one now, another in a half hour and another a half hour after that. a total of 60 minutes has transpired since you got the pills. it's supposed to be 90 minutes... why an hour?
Two hours.
The Answer is 1 hour. Example: You take a pill in 1:00 1st pill: 1:00 2nd pill: 1:30 3rd pill: 2:00 2:00 - 1:00 = 1:00 (1 hour) Final Answer: 1 hour.
One hour.
If you take one now, the next in 30 mins and the last will be taken 60 mins from now, so the answer is 1 hour (60 mins)
The pills will finish in 4 hours and 30 minutes
They will last an hour or 60 minutes.Working it outTake the first pill when the doctor gives the pills to you, take the second pill 30 minutes after that, and the third pill 30 minutes later.
