The best way to solve this is remembering that Hertz (Hz) just means (1/s) so your answer is in (m/s) If you multiple 1m and 5 (1/s) you get 5 m/s the velocity. Cool way to remember v = lambda (wavelength) * frequency.

A 5 Hz is a audio signal but, theoretically, the wavelength is 60 million meters. Not 1 meter.
The speed of sound is about 345 m/s at 22°C

Try frequency times wavelength .

Since f=1/t then t=1/5 (simple cross product)
v=L/t
v=1/(1/5) or 1 meter per 1/5th of segond
v=5m/s
