    If it is eight meters per second, and the total distance he has to travel is four hundred meters to complete the race, you divide the total length needed to travel by the average speed per second to see the amount of seconds required to complete the race at that speed. 8 meters per second: Speed of runner400 meters: Total distance400/8=50.50 seconds to complete the race at the eight of 8m/s.

    8 meters per second: Speed of runner

    400 meters: Total distance

    400/8=50

    50 seconds to complete the race at the eight of 8m/s.
