Given:
An IV medication of 240 mL is to infuse at the rate of 60 mL/hr.
The total infusion time will be as follows:
Volume : Time
60 mL 1 hour
240 mL x hours
So, using the ratio and the proportions, and the cross product:
[tex]x=\frac{240*1}{60}=4[/tex]So, the answer will be: the total infusion time = 4 hours
