A wave has a wavelength of 2mm and a frequency of 3 Hz. At what speed does the wave travel?

I know the answer is 6, because the formula is Speed= Wavelength X Frequency, but I don't know how to write the final answer, it's going to be 6??

Can you help me out, I just don't know how to label the answer.

c = 6 mm/sec

The old name for frequency was cycles/sec.

The new name is Herz and that stands for cycles/sec.

Therefore, wavelength x cycle/sec

2 mm x 3 cycles/sec = 6 mm/sec.
