  1. Shanti had run 4/5 of the race when Nina finished.
    So, if Nina's time was x, it took Shanti 5/4 x to finish the race
    So, Bell had run 5/4 * 600 = 750 meters when Shanti finished.
    That means Shanti was 250m ahead of Belle.

  3. To Chews it 5/4 is used for Shanti because she spent x time for 800m so time for 1000m is 1000/800 x= 5/4 x
