Dionysus, Milil, Sune, and Bast come to a river in the night. There is a bridge, but it can only hold two deities at a time. They have with them a hare who is familiar with the bridge and can navigate it in the dark, and so has to be carried when crossing it.
Dionysus can cross the bridge in 1 minute, Milil in 2 minutes, Sune in 5 minutes, and Bast in 8 minutes. When two deities cross the bridge together, they must move at the slower deity's pace. Dionysus has fed the hare a waterskin of wine.
How can they all get across the bridge in 15 minutes before the hare succumbs to intoxication and loses its bearing?
