Known subclasses: twisted.positioning.base.Climb, twisted.positioning.base.Speed
An object representing the abstract concept of the speed (rate of movement) of a mobile object.
This primarily has behavior for converting between units and comparison.

| Method | inKnots | Returns the speed represented by this object, expressed in knots. This attribute is immutable. |
| Method | __float__ | Returns the speed represented by this object expressed in meters per second. |
| Method | __repr__ | Returns a string representation of this speed object. |
