c. If the average basal rate of oxygen consumption for an adult is 15 L/hour, then calculate how many hours of oxygen use will you get from the 4.7 L tank?

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  =  

 Hours of oxygen use  =   = 0.3hrs

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.

um i think it might be a car?
