You're asking about the speed of a wave with a frequency of 25 Hz and a wavelength of 8 meters.

Here's how to calculate the wave speed:

Formula:

* Speed (v) = Frequency (f) x Wavelength (λ)

Applying the formula:

* v = 25 Hz x 8 m

* v = 200 m/s

Therefore, the speed of the wave is 200 meters per second.
