Answer 1

A shout down a well produces an echo in 2.00 seconds. How deep is the surface of the water in the well? Assume the speed of sound to be 343 m/s.

distance=time*speedsound

solve for distance. Then, well depth is one half distance.

Answer 2

so, in other words your saying 343*2.00 so we get 686, then half it?
to get 343 again.
