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 the 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?
In one minute, one germ becomes two germs. In other words, the number of germs doubles by the minute. Straightforward, right?
It takes a full hour to fill the jar when you start with one germ, so...
The answer is 59 minutes.
It takes one minute for a single germ to split into two. Therefore, starting with two germs instead of one only saves you one minute.
