This IV order specifies the total amount of fluid to be infused and the amount to be given per hour (milliliters per hour). To calculate the duration of infusion (number of hours), simply divide the total volume (1500 mL) by the volume per hour (75 mL). Therefore, 1500 mL ÷ 75 mL/hour = 20 hours to infuse.
