Answer:

Frequency basically means how many waves there are per unit time. For Hz hertz, it means oscillation per second.

Wavelength means the distance travelled by one waveform. I'm assuming that you mean wavelength λ = 1.2 meters.

By simple deduction, as one wavefrom travels 1.2m and 256 waves are generated per second, we can say that the sound wave travels at 1.2 * 256 = 307.2 meters per second. So speed is 307.2 m/s.

This is actually a formula for the speed of waves in general: v = fλ , where f is the frequency and λ is the wavelength.
