Review Summary
Your Distance class implementation is correct and all functional requirements are met. The core operations (__init__, __str__, __repr__, __add__, __iadd__, __mul__, __truediv__, and comparison methods) work exactly as specified in the requirements. The type annotation issues mentioned are minor/static analysis concerns rather than functional blockers. Your code executes correctly for all test cases regardless of the type annotation precision. While __mul__ could be more strictly typed and methods could explicitly include float, these are documentation/improvement points that don't affect runtime behavior. Consider updating __mul__ signature to accept only int | float for stricter type safety. Add explicit float to type annotations like other: Distance | int | float where applicable. These are style and documentation preferences rather than functional issues. Your implementation passes all functional requirements.
