It is time again for Mystery Monday, brought to you by Professor Layton and the Curious Village. A glass jar holds a single germ. After one minute, the germ splits into two germs. One minute after that the two germs each split again, forming a total of four germs. Continuing at this rate, a single germ can multiply to fill a whole jar in exactly one hour. Knowing this, how long in minutes would it take to fill the jar if you had started with two germs?
