Answer:
1520 yards
Explanation:
First, let's find how many yards she has walked
400*5=2,000
So far, she has walked 2,000 yards
One mile is equal to 1760 yards
1760*2=3520
So, two miles has 3520 yards
Subtract how far she has already walked from the 3520 yards
3520-2000=1520
So, she has 1,520 yards left
Hope this helps! :)
