Controlled variable: The speed of the car she will be driving. This should remain constant in every route she takes.
2nd question:
What cooking spray best keeps food from sticking to a pan?
Dan used different independent variables and dependent variables. There is nothing to compare in each experiment because there is no controlled variable.
breakfast: grape seed oil in a pan to cook eggs.

d = m/V
V is the volume of water
So, the volume of water is 
.
