Respuesta :

Answer: D. 300 seconds

2-1=1 which means if Britney is swimming 2 m/s against a current of 1 m/s, she will be swimming at 1 m/s

Answer:

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,
