Ahunter is standing on flat ground between two vertical cliffs that are directly opposite one another. he is closer to one cliff than the other. he fires a gun and, after a while, hears three echoes. the second echo arrives 1.05 s after the first, and the third echo arrives 0.827 s after the second. assuming that the speed of sound is 343 m/s and that there are no reflections of sound from the ground, find the distance (in m) between the cliffs.
