If represents the time in minutes since the plane has left the terminal building, let be the horizontal distance traveled and be altitude of the plane.

Step-by-step explanation

Step 1.

It is given that denotes the altitude of the plane. As the speed of the airplane is slow during takeoff and landing time, the altitude of the airplane will be less during takeoff and landing when compared with the altitude during the middle of the journey.
