ound travels about 750 miles per hour. If you stand in a canyon and sound a horn, you will hear an echo. Now let's generalize that result. Suppose it takes n seconds to hear the echo. How far away is the canyon wall, in terms of n?

Respuesta :

Answer:

[tex]Distance=0.104\times n (miles)[/tex]

Explanation:

When we hear the echo the sound would have traveled twice between the person and the wall.

Thus if we hear an echo after n seconds we have

[tex]2\times Distance= Speed\times Time\\\\\therefore Distance=\frac{0.208miles/sec\times nsecs}{2}\\\\Distance=0.104\times n (miles)[/tex]
