Answer:
a) 
b) The second runner will win
c) d = 10.54m
Explanation:
For part (a):

For part (c), we know how much time it takes the second runner to win, so we just need the position of the first runner in that moment:
X1 = V1*t2 = 239.46m Since the finish line was 250m away:
d = 250m - 239.46m = 10.54m
