Anna, Brad, Carly, Deonte, and Elijah ran around a track as
part of a fundraiser for the school’s math club. Anna ran
first, and when she was tires, Brad ran. When Brad got
tired, Carly ran, and so on. By the end of the fundraiser,
they had run a total of 30 miles. Anna and Brad combined
ran 12 miles.
Brad and Carly combined ran 10.2 miles.
Carly and Deonte combined ran 12 miles.
Deonte and Elijah combined ran 12.3 miles.
How far did each person run?
