Re: MrRubix's Riddle Thread

explain.

I'll explain if it's right.

If not I'll work on my by hand math skills...alternatively I'll use the pc calculator but oh boy that thing sucks. Alternatively I'll realize my logic is not optimal.

I think it's wrong, but I'm not recalculating it right now XD

Re: MrRubix's Riddle Thread

you know what the REAL solution to all this is.... i'm faster than emerald and fractal. end of story.

Reach: 7.3 is wrong. While you're right that one person gets there in 7.3 using what I think your strategy is, I think you'll find the other takes 8.

Re: MrRubix's Riddle Thread

Put emerald on the handle bars, Fractal on the pegs and have Tass ride his balls off.

Two hours.

Kidding, I see that can't happen anyways.

Yeah it is wrong. I decided I might as well check the calculations again.

I think I can fix it though. Probably not tonight.

Re: MrRubix's Riddle Thread

How about emerald rides the bike, and tass carries fractal. Fractal and emerald would then switch after 10 miles. after 20, they'd switch again, until they reach the point of 30. And tass would carry each of them, and you didn't say he slows down if he carries them.

So:

(Emerald - 5mph for 10 miles) and (Tass carries Fractal, goes 5mph for 10 miles) = 2 hours.

Emerald and Fractal Switch.

(Fractal - 5mph for 10 miles) and (Tass carries Emerald, goes 5mph for 10 miles) = 2 hours.

Fractal and Emerald Switch.

(Emerald - 5mph for 10 miles) and (Tass carries Fractal, goes 5mph for 10 miles) = 2 hours.

So the final solution would be 6 hours. I'm not sure if this is the correct way though. But it looks like the optimal choice.

Re: MrRubix's Riddle Thread

He did say, "the bike can only carry one person at a time," which probably means it'll break if more than one person is on at the same time.

If only this was easy like the "multiple people doing one job" problems in algebra.

Re: MrRubix's Riddle Thread

Tass would be walking, and he'd be carrying fractal/emerald at different intervals. Only one person ride the bike.

Re: MrRubix's Riddle Thread

If you think that way, then might as well say everyone on Tass and it'll be the same thing...

Ok, if I correct the error I seem to get 7.6 hours. I guess this is wrong, given other people have said it.

If there's a more complicated way of dealing with this for an optimal path I'll be interested in seeing the answer.


Personally, I assume everyone finishes at the same time. There's no benefit of having someone arrive at the finish before the others, since Tass can wheel the bike back to someone. Parsimoniously speaking, Tass should only backtrack on the bike once. Also, parsimoniously speaking, Tass should backtrack on the bike at the exact point when it will take the person he took the bike from the same time to reach the finish that it will take Tass to backtrack, give up the bike and then reach the finish with the other person.

If you work this out the answer is 7.6

Re: MrRubix's Riddle Thread

@Netjet:

He didn't say they COULD be carried either...

And even if they could, why would they need to switch? Tass walks at the same rate that either of the others rides. He could carry the whole way.

@thread:
I don't think it's possible to get below 7.6 hours... What am I missing?

Re: MrRubix's Riddle Thread

Oh yeah they wouldn't need to switch :/

[MahouMinachan]

Re: MrRubix's Riddle Thread

Okay, I really think the optimal is 7.6 hours.

Re: MrRubix's Riddle Thread

First Idea:
The aim is to get the last person to arrive as quickly as possible. People

Im guessing the idea is that one rides the bike and then drops it, leaving the other to pick up and ride it. As far as im concerned Tass should walk the full distance, as when ever he rides the bike the others have to walk, which means they will arrive later.

So Tass gets there in 30/5, or 6 hours.

The other two I guess, as there stats are even should ride equal distances. So I say that they both take 15/5 + 15/3 hours each. Crap 8 hours.

Will post second hopefully better idea later.
