Linda, Rumi, Liz, Amy, Adam, and Sam ran an 800-meter race. Adam BEAT Liz by 7 meters. Sam beat Linda by 12 meters. Adam finished
5 meters AHEAD of Amy but 3 meters BEHIND Sam. Rumi finished HALFWAY between the first and last woman. In what order did the women
finish? What were the distances between them?
That "person"/THING is WRONG!
Participation Order:
1: Sam
2: Adam - 3 m behind Sam
3: Amy - 5 m behind Adam, and 8 (3 + 5) m behind Sam
4: Liz - 7 m behind Adam, and 2 (7 - 5) m behind Amy
Linda - 12 m behind Sam, and 2 [(12 - (2 + 5 + 3)] m behind Liz
Now, with Rumi finishing HALFWAY between the first and last woman (assumed to be Amy and Linda, considering Sam is male),
Rumi would finish HALFWAY between the SUM of the distances between Amy and Linda, or  =  = 2 m
2 m between Amy and Linda is actually Liz’ position. So, it appears that Rumi and Liz came up TIED for 4th.
Assuming Sam is male, and Rumi is female, then it’s:
3rd: Amy
4th: Liz and Rumi (TIED), and 2 m behind Amy
6th: Linda - LAST, and 2 m behind 4th-place TIED runners, Liz and Rumi
