Answer:
-1 1/3
Step-by-step explanation:
Dear Carlaac04,
To answer this questions you need to know that there are 1,760 yards in a mile. Multiply that by 2 and you get 3,520 yards. Next you multiply 400 by 5, because the each track is 400 yards and Keisha walked 5 tracks, which is equal to 2,000. Lastly, you subtract 2,000 from 3,250 which is equal to 1520 yards.
