There is a concert in the town square. In front of the stage is a grandstand for the audience, and behind the grandstand is the palace that reflects the sound back towards the audience. A listener at some distance from the stage hears the music in such a way that each tone emitted by the orchestra is repeated after a time of 0.8 s. How far is the palace from the listener? The speed of sound is 340 m/s.
