CREATE TABLE table_22842 ("Rank" FLOAT, "Race Number" FLOAT, "Name" TEXT, "NOC" TEXT, "- 250m" TEXT, "- 500m" TEXT, "- 750m" TEXT, "- 1 , 000m" TEXT)

If -750 is 45.505, what is the maximum rank?
SELECT MAX("Rank") FROM table_22842 WHERE "- 750m" = '45.505'
SELECT MAX("Rank") FROM "table_22842" WHERE "- 750m" = '45.505'
