# Exercise 49 - Chapter 2

edited June 2018

Which distance is bigger under the above description, $$d(Spain, US)$$ or $$d(US, Spain)$$ ?

description of d(A,B) “I will put you in an arbitrary part of A and you just have to get anywhere in B; what is the distance in the worst-case scenario?”

$$d(US, Spain)$$ is bigger because US is larger. It takes longer to cross the entire US than the entire of Spain, since we have to cross the sea in both cases and can pretty much ignore it.
