[Marvel] What is the maximum ground speed Spider-Man could achieve while swinging?

Well, since he gets his speed by falling, and then changing direction from vertical to horizontal, I'd say about 300MPH if he made himself as aerodynamic as possible. 120MPH if he isn't worrying about aerodynamics.

Source: Terminal velocity while skydiving is typically 120MPH, but you can get up to 300MPH if you make your body vertical.
