# A Race Around the Globe

Algebra Level 3

Alice, Bob, Carly, and Dave are in a flying race!

Alice's plane is twice as fast as Bob's plane.
When Alice finishes the race, the distance between her and Carly is $$D.$$
When Bob finishes the race, the distance between him and Dave is $$D.$$

If Bob's plane is three times as fast as Carly's plane, then how many times faster is Alice's plane than Dave's plane?
