Answer:
[tex]\frac{3}{8}\ mile[/tex]
Step-by-step explanation:
-Amy walks a distance of 7/8 mile
-Tom walks a distance of 4/8 mile.
#We immediately notice that Amy has walked a longer distance than Tom.
We subtract Tom's distance from Amy's to find how much further Amy walked;
[tex]\bigtriangleup d=d_A-d_T\\\\=\frac{7}{8}-\frac{4}{8}\\\\=\frac{3}{8} mile[/tex]
Hence, Amy has walked 3/8 miles further than Tom has.
