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 the altitude of the plane.
Step-by-step explanation
Step 1.
From the given information denotes the horizontal distance traveled.
Also, it is given that the airplane travels miles an hour.
So, when the time increases, the number of miles traveled by the airplane increases.
Thus, the rough graph of is shown below:
From the above graph, the increasing curve represents the distance travelled by the airplane in one hour.
