The answer is C.

The equation that represents Ellen's speed is t=11m+8

So if you plug in 2 for miles in both equations

Ellen:

t=11 (2) + 8

t=22+8

t=30

Oscar

t=10 (2)

t=20

Ellen ran 2 miles in 30 minutes while Oscar ran in 20 minutes. So if it was 2 miles, Oscar would've finished before Ellen
