Grammar question

FARTHER/FURTHER: according to the AP style guide you use “farther” to refer to physical distance and on “further” to refer to an extent of time or degree. So you had to wait a further two hours past the appointed time because I had hiked 10km farther than I expected.

So, what happens if the extent of degree is also a measure of physical distance?

Sam went 10km _______ than I did, so he was _______ from the start than I was. How do you fill that in?

Bonus grammar note: Whose/Who’s

Whose means ‘of whom’: Whose house is that? I don’t know whose it is. This is the possessive.
Who’s is a shortened form of ‘who has’ or who is, and does not denote possession.

This always messes me up because I secretly think that “its” is the only case where the apostrophe is not used for the possessive.
