The altitude of the plane and
The speed of the plane
The distance from the plane to the station
Step-by-step explanation
Step 1.
Write the unknown quantities
Let us assume the distance from the station to the plane is
then, the rate at which the distance from the plane to the station is increasing when it is away from the station.
That means
when ,
Find the rate of change of distance
Hence, the unknowns in the given problem is
