Question

A hiker hikes to a canyon and yells "hello" into the canyon wall. She carefully times how long it takes for the sound to return to her ear. She hears her echo in .6s. With a known velocity of sound on this day of 340m/s, how far did the sound wave actually travel?

Answer 1

The distance covered by the sound wave is 102 m.

Step-by-step explanation:

The velocity of sound on a particular day, v = 340 m/s

The echo heard by a hiker is, t = 0.6 s

The distance covered by the sound after hearing an echo is 2d say. The speed of sound is then given by :

`v=(2d)/(t)\\\\d=(vt)/(2)\\\\d=(340* 0.6)/(2)\\\\d=102\ m`

So, the distance covered by the sound wave is 102 m.
