2. Amount of soil provided.
In order to give different pH values of the soil, the amount of soil can directly affect this independent variable.
The answer would be 254,340,000
Calories used = Activity level*Weight*Duration
Activity level at 8 min/mile = 0.22 calories per minute
Weight = 180/2.2 = 81.81 kg
Duration = 8 minutes
Substituting;
Calories used = 0.22*81.81*8 = 144 calories
