If you shout across a canyon and hear the echo 0.80 second later, how wide is the canyon?
Well if you know the speed of sound, you can determine how many miles the sound's path was if you know the time it took.
tHE SPEED OF THE SOUND IS 332 M/S
Well if you have the speed of sound and the time.... you can determine how far the sound traveled.
Remember that it travels across the grand canyon and back in that 0.8 seconds so its width is 1/2 the distance the sound went.
