How long does it take to infuse 0.5 L at a constant rate of 60 mL/h?

Explanation:
Time required equals volume divided by infusion rate. Convert 0.5 L to 500 mL. At 60 mL per hour, the time is 500 ÷ 60 = 8.333 hours. This is 8 hours plus 0.333 of an hour, and 0.333 × 60 = 20 minutes, so 8 h 20 m. Check: 8 h at 60 mL/h delivers 480 mL, plus 20 more minutes at 60 mL/h delivers 20 mL, totaling 500 mL.
