We are given that an IV of 500 mL is infused in 800 minutes. We are asked to determine the rate of volume per hour of the IV.
To do that we need to determine the ratio between the volume and the time in hours. First, we need to convert the time into hours. We will use the following conversion factor:
Multiplying by the conversion factor we get:
Now, we determine the ratio of volume and time:
Solving the operations:
Therefore, the rate is 37.51 mL/hr.
