Lizzy: A patient is receiving treatment through a saline drip which makes 20 drops per minute. If the treatment lasts 2 hours, and every 100 drops equal 5 ml of liquid, how many milliliters of treatment will the patient receive after the 2 hours have passed?.
Me: Hmmm, let me think. I think this is the detailed solution:
User
The total of minutes the treatment will take is 2 hours x 60 minutes / hour = 120 minutes. After 120 minutes has passed the total amount of drops that the patient will receive is 20 drops / minute x 120 minutes = 2400 drops. Knowing the number of drops, we know that the patient has taken 2400 drops x 5 ml / 100 drops = 120 ml. Final answer: 120.
