We have that the distance Sylvia is closer to the museum equals:
[tex]\frac{3}{8}-\frac{1}{4}=\frac{1}{8}=0.125[/tex]So, she is 0.125 miles closer than John.

To determine the difference between two values, we subtract the smallest value from the greatest value, which gives us the difference between them.
Since 3/8 > 1/4 we subtract 1/4 from 3/8.
