## Homework Statement

An airplane flying horizontally at an altitude of 3 miles and at a speed of 480 miles per hour passes directly above an observer on the ground. How fast is the distance from the observer to the airplane increasing 30 seconds later?

## Homework Equations

## The Attempt at a Solution

When I attempted to draw the picture for this I got a 3, 4, 5 right triangle because the altitude is 3, and if you divide 480 by 60 you get 8 and half of that is 4. So this would create a 3, 4, 5 right triangle? Now would I use the distance formula with respect to distance?
