Asked by Steven

Nina, Shanti and Belle run a 1000 m race at a constant speed. When Nina crossed the finish line first, she was 200 m ahead of Shanti and 400 m ahead of Belle. When Shanthi crossed the finish line, how far ahead of Belle was she?
Answered by oobleck
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.

How did you get 5/4 oobleck?
Answered by Aurora
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
