One wavelength.

A wave travels one wavelength each period. If a wavelength is two feet, the wave goes two feet every period.
If the frequency is 10 Hz, the period = 1/freq = one tenth of a second. velocity = wavelength / period = 2/(1/10) = 20 feet/second. distance = velocity * time = 20 * (1/10) = 2 feet.
All electromagnetic waves (including light) travel at the speed of light: 299,792,458 m/s (in a vacuum, almost the same in air or anything).

A good equation to remember with regard to waves is,
f*L = v ; where f = frequency, L = wavelength, v = speed
(typically, instead of L for wavelength, the Greek lambda is used.)
Also, in general one should also remember D = R*T,
distance = rate (times) time
hence, to answer your question use,
D = f*L*T
