The problem: Criminals are planning to steal gold bars from a bank and want to work out how many bars they can drive away in the getaway car without getting stopped by the police. The car can be driven at a maximum speed of 140kph. The car must not be driven any slower than 100kph and each gold bar slows the car down by 2.5kph.
