Answer:
The domain is the speed of the airplane.
The range is the distance travelled by the airplane.
Explanation:
From Theory of Values, the domain of a function is the set of independent values, whereas the range of a function is set of dependent values, that is, values associated to one distinct element from domain. In this case, the independent variable is speed, whereas the dependent variable is the distance travelled by the airplane, since it is described in terms of speed.
Hence, the answer to this exercise is:
The domain is the speed of the airplane.
The range is the distance travelled by the airplane.
