Answer:

Speed = 80 m/s

Step-by-step explanation:

The formula to find the speed of a wave is found by

Speed = Wavelength x Frequency  where the frequency is in HZ and the wavelength is in meters

Speed = 200 * .40

Speed = 80 m/s

Here is your answer

We know that

Velocity = Frequency × Wavelength (all in SI units)

V= 200×0.40

V= 80m/s
