Review Summary
The Distance class implementation is working correctly and meets all functional requirements. All magic methods (__init__, __str__, __repr__, arithmetic operations, and comparison methods) are properly implemented, and the type annotations correctly exclude Distance from __mul__ and __truediv__ as specified. There's one minor style note: the __iadd__ method contains an unnecessary else statement. Since the if branch always returns, the else is redundant. You can simply place the else body directly after the if block. However, this is a cosmetic issue that doesn't affect functionality—all tests pass and the code works as intended. Great work on the implementation!

This uses an unnecessary else statement. Per checklist item #1, avoid else by restructuring. Example: use a ternary for the value and add it once, or return early after the if block.
