A classical mechanics problem by Mr X

You fill a cylindrical water tank, with the bottom securely closed, with 5 minutes of constant water flow from the top.

You turn off the flow at the top, and let the full tank drain freely by the force of gravity, through a pipe on the bottom. It takes 10 minutes to empty the tank.

If this pipe is accidentally left open when the tank is being filled, how long will it take to fill the tank?
