Two-out-of-tune flutes play the same note. One produces a tone that has a frequency of 258 Hz, while the other produces 266 Hz. When a tuning fork is sounded together with the 258 Hz tone, a beat frequency of 3 Hz is produced. When the same tuning fork is sounded together with the 266 Hz tone, a beat frequency of 5 Hz is produced. What is the frequency of the tuning fork?
