A naturally occurring whirlpool in the Strait of Messina, a channel between Sicily and the Italian mainland, is about 6 feet across at its center, and is said to be large enough to swallow small fishing boats. The speed, s (in feet per second), of the water in the whirlpool varies inversely with the radius, r (in feet). If the water speed is 2.5 feet per second at a radius of 30 feet, what is the speed of the water at a radius of 3 feet? *​
