Answer:
B. 0.055 second.
Step-by-step explanation:
We have been given that Nancy's 50-meter freestyle swim time was 28.004 seconds. Betty’s 50-meter freestyle swim time was 27.949 seconds.
To find the difference between Nancy’s and Betty’s swim times, we need to subtract 27.949 from 28.004.
[tex]\text{Difference between Nancy's and Betty's swim times}=28.004-27.949[/tex]
[tex]\text{Difference between Nancy's and Betty's swim times}=0.055[/tex]
Therefore, the difference between Nancy’s and Betty’s swim times is 0.055 second and option B is the correct choice.
