Given information
A plane flies horizontally at an altitude of 
and passes directly over a tracking telescope on the ground. When the angle of elevation is 
, this angle is decreasing at a rate of 
. How fast is the plane traveling at that time?
Step-by-step explanation
Step 1.
The side of the triangle remains constant. The 
side is increasing and 
is the horizontal speed of the plane (P), which we want to find at the moment 
.
is decreasing, so
