What is the speed of a wave whose frequency and wavelength are 500 Hz and 0.5 m, respectively?

Like arbiter00.. said, the speed of a wave is the wave's wavelength times (multiplied with) the frequency at which the wave is traveling. Wavelength is usually characterized by the Greek letter Lamda and f for frequency.
The answer to your question is 500(Hz)x.5(m)= 250(m\s).
The seconds (s) in the unit meters per second comes from the inverse of T (time in s) which f is equal to. Hence, you have meters (m) per second (s)!

Please recall your basics!
You say your wave travels 500 wavelengths in a second (that's the implication of frequency) and wavelength is 0.5 m, so speed is 500x0.5=250 m/s. Elementary, isn't it!
