A certain type of water lily doubles the area it covers every year. Ten years after being planted in our lake the water lilies cover a quarter of the lake's surface. How many more years will it be before they cover the entire surface of the lake?

2 years. The first time it would go from a quarter of the lake to half. The next year it would double that, taking over the whole lake.
