Answer:

Speed = 20 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 =  .80*25

Speed = 20 m/s

Here is your answer

We know that

Velocity = Frequency × Wavelength (all in SI units)

V= 25×0.80

V= 20m/s
