Velocity, v, distance, d, and time, t, relationship:
Distance to and from wall = 2d (there and back)
Velocity = v
A student standing in a canyon yells "echo", and her voice produces a sound wave of the frequency of f= 0.55 kHz. The echo takes t = 4.5 s to return to the student. Assume the speed of sound through the atmosphere at this location is v=324 m/s.
f = 0.55 kHz
t = 4.5 s
v = 324 m/s
Write an expression for the distance, d, the canyon wall is from the student.
