How to find the wavelength of a sound wave?

  1. 1. The problem statement, all variables and given/known data
    What is the wavelength of a 25 Hz sound wave? What is the wavelength of a 4.5 kHz sound wave?

    2. Relevant equations
    wavelength = velocity / frequency or λ = v/f

    3. The attempt at a solution
    I know that I'm supposed to plug the 25 into the equation, but he didn't give us a velocity, so now I'm stuck. That's what I need help with. :/
    The speed of sound is 340 m/s
    is that what I'm supposed to use for velocity?
