12m east / 3m north does not make any sense, since vector division is undefined. You might be thinking about the derivative which has no units in this case.

- lupire 5y agoYou're missing the point. The units are useful because they express direction.
- OscarCunningham 5y agoYou can divide by a vector of a 1-dimensional vector space, which is all units really are. https://oscarcunningham.com/4/dividing-by-a-vector/ https://oscarcunningham.com/4/dividing-by-a-vector/
- anonytrary 5y agoHow is that relevant here? We're talking about a two dimensional vector space (hence "east", "north").
- OscarCunningham 5y agoSince we've chosen a basis of the vector space (east, north) we can think of it as two 1-dimensional vector spaces. So we're dividing meters east by meters north.
