A mirror faces a cliff located some distance away.  Mounted on the cliff is a second mirror, directly opposite the first mirror and facing toward it.  A gun is fired very close to the first mirror.  The speed of sound is 343 m/s.  How many times does the flash of the gunshot travel the round-trip distance between the mirrors before the echo of the gunshot is heard at he location of the second mirror?
