Answer:(my calculations) 13 hours and 19 minutes
Explanation: now this may not be completely accurate.... but if the infusion time is the total volume (mL) divided by the flow rate (mL/hr)... that would make it 13.33333... now 13 hours and .33 (rounded) is left...however, you need the minute too. so .33 of an hour roughly changes to about 19 minutes. so my answer would be 13 hours and 19 minutes. as I said before this information might not be accurate so my apologize if I am wrong.
