How long will it take to use all of the saline solution? Give you answer in hours and minutes.

Question

Doctors use intravenous (IV) drips to deliver fluids and medications to patients. Suppose an IV drip starts with 1,000 ml of saline and dispenses fluid at a rate of 2.5 ml per minute.

Answer 1

2.5 ml/min (x min) = 1000 ml

x = 400 min

400 min x 1 hr/60 min = 6.67 hours

0.67 hours x 30 min/ hr = 20 min

ANSWER = 6 hours 20 minutes
