If the $GPS woman runs up the stairs with twice the speed, her gain in gravitational potential energy remains unchanged at 4500 J because gravitational potential energy depends only on the mass of the body, the height gained, and the gravitational field strength (g), not on the time taken or the speed of motion. So even if speed is$GPS increased, the work done against gravity to reach the same height stays the same.
