Synopsis: Jimmy Olsen and a Roman charioteer become exchanged in time as a result of the activities of Anachronids, faster-than-light robots who have appeared in the Earth-One universe. To counteract the time-warping effect, the Guardians of the Universe enable Flash and Superman to race in the opposite direction, and the two heroes make it a competition against each other. Both save each other from perils along the way, but Jimmy Olsen finds himself condemned to death by a Roman general as a sorcerer, and facing a firing squad of bowmen.
Synopsis: Student-secretary Joanie Swift is typing a list of time-space equations for physics Professor Winklerod when she stumbles across the Speed Formula. Realizing she has the same powers as Johnny Quick, she creates a similar costume and proposes they form a team. Eventually, the effect wears off and Joanie is unable to retrieve the formula.
