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.

$\text{Difference between Nancy's and Betty's swim times}=28.004-27.949$
