A certain dog whistle operates at 22.75 kHz, while another (brand X) operates at an unknown frequency. If neither whistle can be heard by humans when played separately, but a shrill whine of frequency 6000 Hz occurs when they are played simultaneously, estimate the operating frequency of brand X. Find your answer in kHz
