Try this one, which you should memorize:
(frequency)*(wavelength) = wave speed
The trick is to know that, for the fundamental frequency, the wavelength is twice the length of the string, because only a half-wave is vibrating.
A typical steel B-string in a guitar resonates at its fundamental frequency at 240 Hertz. The length of the string is 0.620 m. What is the wave velocity along the string? Find your answer in m/s.
