If Britney can average  2.0 m/s for 300 m At that speed for just a 100 m Long course, she could have the Record at 50.0 s, and that's assuming the turn doesn't affect her speed in a negative way.  The current  Record for 100 m Freestyle for women is: 52.07 s.
So your answer is 100 seconds, do you understand?
