bob is watching a comet from the ground with a telescope. The comet is soaring at a constant altitude of 7000 miles at a speed of 10000 miles per hour towards the point directly above him. When the comet is 25000 miles away, at what rate is the distance of the comet changing?
If the rate that the distance of the comet is changing is 960 miles per hour, at what rate is the angle of her telescope changing?
