In a gardening community, members decided to create a pond using water from a spring. All the water from the spring was directed into the pond via a pipeline, and the pond started to fill with water. As a result, the pond was filled to $2 / 3$ of its volume after $t = 16$ days. At this point, it was noticed that one quarter of the water from the spring was leaking through the pipeline.
