The rate that the transmitted VOR variable signal rotates is equivalent to how many revolutions per second?

In VOR, the bearing information comes from a rotating variable signal that is synchronized with a reference signal. The rate at which this variable signal rotates is fixed at 30 revolutions per second, driven by a 30 Hz oscillator. Each complete rotation changes the phase relationship between the variable and reference signals by 360 degrees, and that changing phase is what the receiver uses to determine bearing. So the correct rate is 30 revolutions per second (which equals 1800 RPM, but the question specifies per second).
