The wave travels one wavelength in the time of one cycle, which is 800cm in 1/20 second, ie 8m / 0.05s or 8*20 = 160m/s

if it is is a electromagnetic wave it is going the speed of light if in a vacuum

V = λ*f = 8.00 m*20 sec^-1 = 160 m/sec

20/sec * 8 m = 160 m/sec follow the units and you will get the answer pretty easily.

V = 8 x 20 = 160 m/s

160 metres per second velocity = frequency x wavelength v = 20 x 8
