You are police officer who just showed up to a crime scene where the instructions for disarming a bomb are left. The bomb is sitting in front of a large fountain of water. Also, two large bottles are near the bomb. One bottle has a capacity of 5.2 gallons while the other has a capacity of 4 gallons. Both contain a mark which indicates when the bottle is full. You must fill one of the bottles with exactly 2.4 gallons of water and then place the bottle on top of a scale that is sitting next to the bomb to disarm it. Unfortunately, you don’t have time to go get any other measuring tools. How can you be sure to put 2.4 gallons in one of the bottles of water before the two minute timer runs out?
