Calculate the wavelength of the signal sent by Q101 assuming that the actual frequency is 101.1 MHz. Determine how long it would take the signal to reach a car 33.4km away from the station.

    c = fw
    c = speed of light (3E8 m/s)
    f = frequency in Hz (convert MHz to Hz)
    w = wavelength in meters.

    For time,
    distance = rate x time.
    d = 33.4 km converted to meters.
    r = 3E8 m/s
    t = seconds.
