Answer:17.08 s
Explanation:
Given
distance between First and second Runner is 45.6 m
speed of first runner =3.1 m/s
=3.1 m/s
speed of second runner =4.65 m/s
=4.65 m/s
Distance between first runner and finish line is 250 m 
Second runner need to run a distance of 250+45.6=295.6 m
Time required by second runner 
time required by first runner to reach finish line
Thus second runner reach the finish line 80.64-63.56=17.08 s earlier
