Review Summary
The Distance class implementation is functionally correct - all magic methods (add, mul, truediv, comparison operators) work as specified for both Distance and numeric operands. While the type annotations on __add__, __mul__, and __truediv__ methods could be more precise by using int | float instead of just int, and adding from __future__ import annotations would improve type hint safety, these are code quality improvements rather than functional blockers. The runtime behavior matches requirements, and the core functionality is solid. The code is approved as it meets the functional requirements specified in the task.

Missing from __future__ import annotations at the top of the file. This can cause NameError: name 'Distance' is not defined when using Distance in type annotations (checklist item #1.2).

Type annotation other: int should be other: int | float or other: Union[int, float]. The method should accept both integers and floats (checklist item #1.1).
