If you hear an echo one-second after your holler is reflected from a canyon wall 150 meters away, how fast is your voice travelling?
How does a wave's speed relate to its frequency and wavelength?

If you are standing 150 m away and hear the echo after 1 second, the velocity of sound in air is 300 m/sec and is approximately correct.
Velocity = frequency x wavelength

The voice travels to the wall (150m) and back (150m) in one second.
m/s = 300m/s
