If a person's average speed for a 10.00 kilometer race is 5.644 meters per second, what was her winning time?

• Pre AP Physical Science -

distance = rate x time
10,000 meters = 5.644 m/s * time(s)
Solve for time (in seconds).
Change to minutes, if disired, by dividing time in seconds by 60 seconds/min.
