Answer

Beat frequency = 15 Hz Beat frequency two octaves lower = 3.75 Hz

Work Step by Step

The beat frequency is the difference, or 15 Hz. If each frequency is reduced by a factor of 4, the difference between the new frequencies is also reduced by a factor of 4. The new beat frequency would be (15 Hz)/4, or 3.75 Hz.
