You can have as many controls as necessary, But they must remain equal at all times in order to get the most accurate results
Energy is not created or destroyed due to the law of Conservation of Energy. Hope this helps!
The average speed is calculated using the following formula
Where

T = 298 K [room temperature]
m = mass of each molecule of oxygen
mass of one mole of oxygen molecules = 32 g / mol
mass of one molecule of oxygen will be = 
mass of one molecule of oxygen will be = 
putting values
average speed = 
Average speed = 482.19 m / s
average speed = 1735.8 km / h
so approx = 1700 km/h
