Answer:

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
