The speed of a wave is determined by the product of the frequency and the wavelength; we already have the wavelength and the frequency, so all we need to do is multiply them by each other and use our proper unit of measure.
Velocity (speed) = Frequency x Wavelength
V = 250 x 6
V = 1500
Your answer is 1500 m/s.
I hope this helps!

What is the question?
Explanation:
If you tell me the question I can help.
The direction of the friction force is the same than the movement, but its sense is the opposite.
