Answer 1

87.5 m/s

Step-by-step explanation:

The speed of a wave is given by

`v=\lambda f`

where

v is the wave speed

`\lambda` is the wavelength

f is the frequency

In this problem, we have

`f=250 Hz` is the frequency

`\lambda=0.35 m` is the wavelength

Substituting into the equation, we find

`v=(0.35 m)(250 Hz)=87.5 m/s`
