A source of oscillations with a period of T = 0.005 s causes a wave with a wavelength of 7.175 m

A source of oscillations with a period of T = 0.005 s causes a wave with a wavelength of 7.175 m in water. What is the speed of sound in water?

T = 0.005 s.
λ = 7.175 m.
V -?
The speed of propagation of a wave in a substance V is determined by the formula: V = λ * v, where λ is the wavelength, v is the frequency of the wave.
The frequency of the wave v is determined by the formula: v = 1 / T, where T is the oscillation period.
V = λ / T.
V = 7.175 m / 0.005 s = 1435 m / s.
Answer: the speed of sound in water V = 1435 m / s.
