5. You are hiking in a canyon and you notice an echo. You decide to let put a yell and notice it took 2 seconds before you heard the echo of your yell. How far away is the canyon wall that reflected your yell?

Answer 1

1 second each way

d = v *(1second)

where v = speed of sound
maybe around 340 meters/second

so I guess around 340 meters

so what was the problem?
