I was taking a journey the other day and turned to my mum and said which would be the quickest way to get there, by train or car? In a deadpan voice with a look of confusion on her voice she told me trains because they travel quicker.

Cue me being highly embarrased whilst laughing my head off. Obviously I knew the answer to the question really but for some reason decided to have a brain meltdown. :D

Please Help.
Thanks !

I didn't find the right solution from the internet.
