Question

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?

Answer 1

`Distance=0.104* n (miles)`

Step-by-step 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

`2* Distance= Speed* Time\\\\\therefore Distance=(0.208miles/sec* nsecs)/(2)\\\\Distance=0.104* n (miles)`
