Given information
An airplane takes off from an airport and lands an hour later at another airport, miles away.
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 known that the ground speed is the relative speed of the airplane to the ground.
The ground speed of the airplane will be slow at the time of take-off.
The rough graph of ground speed is shown below:
From the above graph, we can observe that there is a variation in the ground speed of the airplane during the take-off and landing time.
