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. How deep is the Grand Canyon at a spot where you can hear your echo 5.2 s after you shout?

Answer 1

Answer:

884m

Explanation:

multiply it and divide it by 2 as it goes down and up (the sound) plz give 5 star's

Answer 2

Answer:

v=340m/s

time to reach the bottom = 5.2/ 2= 2.6s

now s= D/t therefore D= s× t = 340×2.6m= 884mts.
