When fired from a gun, the hunter also produced a sound wave. The length of this wave does not matter, since we are dealing with stationary objects. From the problem it follows that in 1 s the wave managed to pass from the hunter to the mountain and back. That is 170 meters per second, and this is the dimension of speed in the SI system. Answer: speed 170 m / s.
