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.
First off there are 3520 yards in 2 miles. Now we need to figure out how many yards she has walked (400 x5=2,000) she has walked 2000 yards so far. Now we need to know how many more yards she needs (3520-2000=1520) then we divide to figure out how many times around the track (1520/400=3.8) She needs to go roughly 4 more times around the track to go 2 miles :)
