Rubik’s Cube Contest
The six top finishers in a Rubik’s cube contest solved the cube in 0:35, 0.53, 1:22, 1:36, 2:04, and 2:38. Each started by completing a different top color: blue, green, orange, red, white, and yellow. Of the six, three began K4 together (Nicole, Grace, and Sara), and three joined the class (Lori, Becky, and Brookelin). From the information given, determine how long it took for each girl to solve the cube and what color each one used as a top starting color.
