Airspeed question

[TBK]

Is the air from our lips at 300MPH when we whistle? The whistle has other
causes. Hemholtz resonator, etc. (Coke bottle). Many people substantial
claims with complete true assertions. Of course the two don't go together.

Why do we have five fingers? Because Jello is flat. Both true.

Maybe some fluid dynamics or the such genius out there can help you.
