Speaker Beats

    A speaker at the front of a room and an identical speaker at the rear of the room are being driven by the same oscillator at 464 Hz. A student walks at a uniform rate of 1.67 m/s along the length of the room. How many beats does the student hear per second?

    I have gotten this far its just i dont know where to go from here..simply i dont no how to find v, is it jsut speed of sound ??

    F=464 Hz
    u=1.67 m/s

    Fhi= f(1+u/v)

    Fbeat=/ Fhi - Flow / = (2*f*u)/v

    Whats v??
