If you shout across a canyon and hear the echo 0.80 s later, how wide is the canyon?

Hi elleprest,

Basically, you need to know the speed of sound to work out this problem. Once you have done so all you need to do is work out distance equals speed x time.

Keep in mind that the sound travels across the canyon and BACK again to the listener.
