Actually, we know that they covered the same distance,right?
However, Steven took a shorter time compared to Michelle.
So, if Michelle took a longer time, we subtract her time from Steven's time so as to get how much faster Steven swam....I hope you get my point.
So, this is what you do 
$$27.3-25.4=answer$$
