A droplet of oil drops onto the surface of a bowl of water. The surface that the oil covers is twice the surface that it covers a minute ago. If it takes 4 minutes to cover the whole surface of the bowl of water, when does the oil cover 1/4 of the surface of a bowl of water?

Doubles every minute        so    at 3 minutes it was   1/2 covered     at 2 minutes it was 1/4 covered
