The fifth puzzle in the new feature from Tom Rocks Maths – check out the question below and send your answers to @tomrocksmaths on Twitter, Facebook, Instagram or via the contact form on my website. The answer to the last puzzle can be found here.
You are responsible for driving an important person across the desert, but the cars that you have been given can only hold enough petrol to cover half of the distance. Being a desert, there are of course no petrol stations along the way. However, you have access to as many cars as you need and can transfer petrol between them.
What is the minimum number of cars that you will need and how can you complete the journey?
The answer will be posted in 2 weeks along with the next puzzle – good luck!
