Review Summary

Your Distance class meets the functional requirements: all arithmetic, comparison, and string/representation methods behave as specified, and __mul__/__truediv__ correctly restrict their argument types and handle rounding. The only remaining issue is stylistic: in app/main.py, inside __iadd__ (likely around the if isinstance(other, Distance): line), you use an else block where the checklist prefers fall-through control flow [CHECKLIST ITEM #1]. A more idiomatic approach would be:

if isinstance(other, Distance):
    self.km += other.km
    return self

self.km += other
return self

Because this is a readability/style concern rather than a functional blocker, your solution is approved, and you can address that else usage as a minor improvement. Overall, you’ve implemented the required behavior cleanly and with appropriate type annotations—nice work.

This violates checklist item #1: "Avoid unnecessary else statements". After if isinstance(other, Distance): self.km += other.km, you can return to the normal flow and use self.km += other without an else block, similar to the provided good example.
