Answer:
0.3hrs
Explanation:
Given parameters:
Average basal rate = 15L/hr
Volume of oxygen = 4.7L
Unknown:
Hours of oxygen use = ?
Solution:
Now to solve this rate problem, we need to find the time;
Hours of oxygen use = [tex]\frac{volume of oxygen }{average basal rate}[/tex]
Hours of oxygen use = [tex]\frac{4.7}{15}[/tex] = 0.3hrs
