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?
