How deep is the Grand Canyon at a spot where you can hear your echo 5.2 seconds after you shout, in meters?

Question

If you shout into the Grand Canyon, your voice travels at the speed of sound (340 m/s) to the bottom of the canyon and back, and you hear an echo.

Answer 1

D = 340  m/s * 5.2 s

 

  = 1768 m

 

 

However, this distance is round trip, down into the canyon and back.

So it must be cut in half.

 

884 meters
