1. The winner's time was 22.5 secs.
2. The second place runner ran 8m per sec until the winner crossed the finish line.



Stmt 1: Insufficient, don't know speed of second runner during this first 22.5 sec.

Stmt 2: Insuff, know rate for interval, but no time.

Together, C. rt=d 22.5x8=180, 20 meters back.


Incidently, how do you ascribe quotes to the original poster with this forum software.?

(C) Both statements together are sufficient

Statement (1) tells us that runner-up finished in 25 seconds, so his average speed was 200/25=8m/s. We don't know whether the rate was constant, so this is not sufficient.

Statement (2) is not sufficient, because the runner-up might have slowed down / picked up the pace during the last 2.5 seconds.

When we combine the statements: the average rate for the race was 8m/s, so it must have been the same during the last 2.5 seconds. => the distance was 2.5*8=20 meters

Until I saw the second condition I thought the answer was either A or D, since I assumed both the runner run at uniform speed through out..But after looking at the second condition my answer is C
