Can you answer the question: 'Which way is the bus going?' The popular puzzle is used in schools to test logic but often leaves adults scratching their heads, while children can solve it easily. The answer to the riddle is in fact simple, but depends on what country you live in.
Answer - If you're in the UK - the bus is travelling to the right. And the key to solving the puzzle is the fact that you can't see the passenger doors. This means they must be on the other side of the bus, and if you're in the UK where people drive on the left side of the road this means the bus is going right.
The opposite applies in the US and other countries where people drive on the right - and the bus would be travelling on the left.
