Review Summary

I am approving your solution because it correctly implements all required behaviors of the Distance class: construction, string/representation methods, arithmetic operations, and comparisons all work as specified. The use of type annotations, numeric handling, and rounding in __truediv__ is accurate and aligns with the task requirements. The only issue identified is a style-related point in __iadd__, where an unnecessary else is used after branches that already return a value, which conflicts with the checklist guideline about avoiding redundant else statements. This is a non-critical, non-blocking style concern and does not affect correctness or functionality. As a future improvement, you can refactor __iadd__ so it uses early returns for the supported types and a final return NotImplemented at the end of the method instead of an else block. Overall, your solution is solid and meets the core functional and checklist requirements, aside from that minor style refinement.

This violates checklist item "Avoid unnecessary else statements": after handling Distance and numeric types, you can return NotImplemented directly without wrapping it in an else, e.g. drop the else: and leave return NotImplemented at the end of the method.
