500W sirens of two ferries approaching each other emit at equal frequency of 300Hz. However the captain of one ferry hears the sound at a frequency of 348Hz, while the captain of the other ferry hears it at a frequency of 347Hz. Find the speed of each ferry. At what distance between the ferries is the sound intensity 82db?
