## Global Stats

Working independently at their respective constant rates, pumps $$X$$ and $$Y$$ took $$48$$ minutes to fill an empty tank with water. What fraction of the water in the full tank came from pump $$X?$$

(1) Working alone at its constant rate, pump $$X$$ would have taken $$80$$ minutes to fill the tank with water.

(2) Working alone at its constant rate, pump $$Y$$ would have taken $$120$$ minutes to fill the tank with water.
