If an individual was exercising at an exercise intensity of 1.5 liters of oxygen per minute, and had a mechanical efficiency of 20 percent, how many heat Calories would this person generate in 30 minutes?

Total calories = 45 calories

Explanation:

Given dа ta:

intensity of oxygen per minute = 1.5 lt

mechanical efficiency = 20%

time = 30 minutes

1 litre of oxygen = 5 calories per minutes

Total calories = oxygen quantity/min * time * efficiency * cal/min

Total calories = 1.5*30*0.20*5

Total calories = 45 calories
