Incorrect, completing the race faster than the rest means you consider those who completed in a shorter duration.

3m + 3m + 3m + 2 x diameter of small senicircles = 28m. You can find out the diameter first, and you can get the radius From there, you can find the diameter, and hence the radius of the large semicircle. Try working on from here :)
