So a rocket is blasting off from earth. You are 10 mi away from the launch pad. the Rocket is moving up at a constant rate of 800mph. What is the rate of change of your angle from the ground to the rocket changing? thanks

Draw a right triangle.
The base is 10 mi.
The altitude is the height of the rocket.
Let the angle of elevation be A.
tan A = h/b
Now differentiate.
Put in the numbers you know.

As a word to the wise. You know, if you google related rates you will most likely find your problem or something very similar. These problems are very cliche in that they are done over and over in calc classes. Also, as pointed out, if you do a search on the site there is a good chance it has already been posted.
