Miles is camping in Glacier National Park. In the midst of a glacier canyon,
he makes a loud holler. The sound (v = 345 m/s) bounces off the nearest
canyon wall (which is located 280 meters away from Miles) and returns to
Miles. Determine the time elapsed between when Miles makes the holler
and the echo is heard. *
V

t=1.623 sec

Explanation:

The distance traveled before the echo is had is:

Given the speed of sound as v=345m/s, we use the speed equation to solve for t:

Hence, it takes 1.623 seconds to hear the echo.
