When it came to speed, who was faster—Superman or The Flash?

The Flash's task was comparatively simple. He only needed to stand to the side of the battlefield, open the suitcase-like object in his hands, and get as close to Superman as possible.
After finding the right spot, he opened the case and let the warm red light shine onto Superman.
