Solution

We can cool a bucket of water quicker when we keep ice inside the bucket because ice cubes absorb more and more heat from the liquid system in which it is present, cooling the liquid system quickly. But when we put water in ice, the ice comes in contact with the bucket and absorbs the latent heat from both the water and bucket. Therefore, the effectiveness of cooling is reduced.
