Is it 6 hours?

In pure mathematical terms, if you switch between Emerald and Fractal riding the bike instantaneously for the entire duration of the trip, then everyone is going 5mph the entire trip, meaning they arrive in 6 hours.

Of course, if you're looking for something that can actually be done in real life, then that isn't possible. But let me bounce some ideas off. Since Tass will always be going as fast or faster than the other two regardless of who has the bike, and the only thing that matters is the time the slowest person gets there, isn't Tass irrelevant? He can never be the last person to arrive, therefore giving him the bike at any point makes it so that the other two only arrive later, lengthening the overall time.

Assuming that's correct, you can completely eliminate Tass from your solutions, as he'll be walking the entire time anyway.
