Barry is observing a bird on the ground 50m away from him. The bird flies away at an angle of 60° from the ground directly away from him. From his point of view, the bird's angle of elevation increases 6º per second. How fast is the bird flying when its angle of elevation from Barry's perspective is 30°?
