In Barry's logic, a speedster is never late nor early. They arrive when they are supposed to. No matter how you look at it, in any medium, the Flash is leagues faster than Superman. The Flash is faster than time itself at top speeds and has traveled back in time and forward. Superman doesn't move fast enough to accomplish such feats, he also has abnormal hearing that allows him to hear longer distances than approximately 2500 km.
But no, Superman isn't anywhere near the Flash's speed.
