maintenance4-2-1? mL/h55 lb

Practice exercise (made-up values, not clinical guidance). A child weighs 55 lb. Using 1 kg = 2.2 lb and the Holliday–Segar 4-2-1 rule, find the hourly maintenance fluid rate R in mL/h.

Practice exercise (made-up values, not clinical guidance). A 500 mL infusion starts at 06:00 at 120 mL/h. After 2 hours the rate is changed to 150 mL/h and is not changed again. How many hours t after the start will the bag be empty? Round to one decimal place.
