Two issues with this quiz: the obvious one is how are we supposed to guess which countries you want us to include? You've omitted Luxembourg and Denmark which are relatively close and have included USA which isn't. Secondly what do your hints mean? Seeing 0 for Ireland, I assumed it was distance (not sure what units) but then why is it 0 for France? And if it's 757 to Belgium, what units are they? The figure is too high to be miles of kilometres. Finally, as a Gibraltarian, I would like to point out that the distance from UK to Spain is also 0 and that morocco is pretty close too.
