p. 266

On p. 266, the practice question asks for the frequency heard by the observer. Shouldn't the velocities in the solution equation be 330 m/s, not 300 m/s?

Thanks for your sharp eye! Actually the passage should say "Assume the velocity of sound in air to be 300 m/s." The equation itself is correct given this change.
