Water lentils
The water lentil reproduces by dividing into 2 every day. Thus on the first day we have 1, on the second 2, on the third 4, on the fourth 8, and so on. If, starting with one lentil, it takes 30 days to cover a certain area, how long will it take to cover the same area if we start with 2 lentils?
