Running After a Fairy

Andrea starts to hear a sound and she can't tell whether it is a buzzing or the most beautiful music she has ever heard. As it gets louder she notices the area around her starting to get brighter. She looks around and sees a fairy, glowing brightly in the dark. The fairy beckons to her, and then flies away. Andrea hesitates briefly, and then runs after the fairy.

How fast does the fairy make Andrea chase her?
