Answer:
In 1 second he runs 6.0 meters.
Step-by-step explanation:
The question asks "how far does he run in one second?" The answer is a distance, not a time, so if it needs to be rounded, it is to the nearest tenth of a meter.
Divide the distance by the time:
(414.2 m)/(68.7 sec) = 6.029 m/sec
In 1 second he runs 6.0 meters.
