The rotors look horrible, a lot of corrosion.
They may be able to be turned but you will have to mic the thickness of the rotor and compare with the specs stamped on the rotor.
I would say you have more than 30 miles but it's hard to tell from the pic. May also be the other side that's registering the pad life indicator.
