You have 500 mL to infuse over 8 hours. What is the infusion rate in mL/hr?

Explanation:
Delivering IV fluid at a steady rate means dividing the total volume by the total time to find how much fluid goes out each hour. Here, 500 mL over 8 hours gives a rate of 500 ÷ 8 = 62.5 mL per hour. This rate, when multiplied back by 8 hours, yields the full 500 mL to be infused. If the rate were higher, more than 500 mL would be delivered in 8 hours; if lower, less would be delivered in that same period.
