How can i get the velocity of waves ?

[Mohamed9005]

Homework Statement

if y =0.03sin(50x-300t) (SI UNITS) , the wavelength of the wave is _______

The Attempt at a Solution

ω=300=2*∏*linear frequency
therefore frequency = 150/∏ hz
then λ=Velocity/frequency

λ=(∏/150)*velocity
i'm stuck here,i seriously don't know how can i get the velocity of the wave
