Hi can anyone solve this??

I couldnt figure out how to use it

Question

Use the wave equation to find the speed of wave given by

y(x,t)=(3.00 mm) sin [(4.00/m)x-(7.0/s)t) ]

I guess the wave equation is ,

(d^2y) 1 (d^2y)

------- = ------ -------

(dx^2) v^2 (dt^2)

can any one solve it step wise?
