    298,300 km/s

    Using mass of 2*10^30 kg

    dump used a mass of 1.979*10^30

    using Wikipedia's mass, 1.989*10^30 297,460 km/s

    EDIT: The Wikipedia article on "solar mass" give a conventionally accepted value that would lead to an escape velocity of 297,450 km/s

    Hi. I would guess about 300,000 km/s.

    It would be greater than the speed of light.
