A stadium of soccer supporters do the “stadium wave” to keep their spirits up during a dull 0-0 draw. The stadium has a circumference of 450.0 meters, and it takes 12.0 seconds for the wave to travel all the way around the stadium. What is the stadium-wave’s average velocity? The answer should have 3 significant figures.
