# Problem: The physical fitness of athletes is measured by "VO2 max," which is the maximum volume of oxygen consumed by an individual during incremental exercise (for example, on a treadmill). An average male has a VO2 max of 45 mL O2/kg body mass/min, but a world-class male athlete can have a VO2 max reading of 88.0 mL O2/kg body mass/min.Calculate the volume of oxygen, in mL, consumed in 1 hr by an average man who weighs 186 lbs and has a VO2 max reading of 47.6 mL O2/kg body mass/min.

We have to calculate the volume of oxygen gas consumed by a man in 1 hour, who weighs 186 lbs and has a VO2 max reading of 47.6 mL O2/kg body mass O2/min.

We can find the volume of oxygen gas consumed using dimensional analysis.

We need to do the following conversions:

• Convert body weight from lb to kg units
• Convert time from hours (h) to minutes (min)
• Find the volume of oxygen gas consumed.
