how long would it take for a toilet that is constantly running to use 60,000 gallons of water?  the incoming line is one quarter inch in diameter, and the water pressure is standard city water pressure.

A long time! About 272 days. I can give you the details of the calculation if you want (ask a follow-up question), but the essential details are that the flow rate = 1 ft/sec for a pressure of 50 psi and a water density of 62 lbm/ft^3 at 70 degrees F with a 1/4" pipe.
