An IV is infusing at 125 mL per hour. It will take how many hours for 1500 mL of fluid to infuse?

To determine how many hours it will take for 1500 mL of fluid to infuse at a rate of 125 mL per hour, one can use the formula:

Total Volume (mL) / Infusion Rate (mL/hour) = Time (hours).

By substituting the given values, 1500 mL divided by 125 mL/hour equals:

1500 mL / 125 mL/hour = 12 hours.

This calculation confirms that it will take 12 hours for the entire volume of 1500 mL to be infused at the specified rate of 125 mL per hour, making the answer correct.
