The 100-Meter-Dash Puzzle

We look at another challenging math problem listed in the book, In Code, by Sarah Flannery.

Albus, Severus, and Minerva ran a 100-meter dash. Each ran at a uniform speed throughout. When Minerva crossed the finish line to win the race, she was 10-meters ahead of Albus. When Albus crossed the finish line to finish second, he was 10-meters ahead of Severus. How many meters was Minerva ahead of Severus, when Minerva crossed the finish line?
