The streets of a metropolis are a square grid that extends infinitely in all instructions. Just one of the streets, Broadway, has a police present stationed just about every 100 blocks.

A robber is somewhere in the city.

Can you devise a technique that guarantees the felony will be noticed by the police at some stage in time?

Relevant details: The robber and the law enforcement officers are in a avenue at all situations. The robber has a finite maximum operating velocity, which is quicker than any officer’s. The law enforcement can see infinitely considerably.

Thanks to Professor Alex Lvovsky of the College of Oxford for this puzzle. Prof Lvovsky is the head of COMPOS, an on the web system that gives totally free tuition in maths and physics for pupils in a long time 10, 11 and 12 (GCSE and A-level). The thought is to help enthusiastic young adults to study these topics at a deep degree, with normal tiutorials by Oxford physics undergraduates and graduates. Registration for the next educational 12 months is open now.

I set a puzzle in this article each two months on a Monday. I’m often on the seem-out for wonderful puzzles. If you would like to advise just one, email me.

I give college talks about maths and puzzles (online and in particular person). If your university (or police academy) is intrigued remember to get in contact.
