Can you solve the bridge riddle?

你能解開橋之謎嗎

來源視頻

Taking that internship in a remote mountain lab might not have been the best idea.?

Pulling that lever with the skull symbol just to see what it did probably wasn't so smart, either, but now is not the time for regrets because you need to get away from these mutant zombies fast.

去深山實驗室實習(xí)也許不是一個好主意。

拉下畫著骷髏頭的控制桿 僅僅為了看看會發(fā)生什么大概也不是什么明智之舉，但現(xiàn)在可不是后悔的時候，因為你得趕緊擺脫這群變異的僵尸。

With you are the janitor, the lab assistant, and the old professor.?

You've gotten a headstart, but there's only one way to safety: across an old rope bridge spanning a massive gorge.?

You can dash across in a minute, while the lab assistant takes two minutes.?

The janitor is a bit slower and needs five minutes, and the professor takes a whole ten minutes, holding onto the ropes every step of the way.

與你同行的還有：門衛(wèi)、助理和老教授。

你們甩開了僵尸，但前方只有一條路橫跨大峽谷的古老的吊橋。

你過橋需要一分鐘，助理需要兩分鐘。

門衛(wèi)慢一點，需要五分鐘，教授需要整整十分鐘，因為他每走一步都緊緊抓住繩索。

By the professor's calculations, the zombies will catch up to you in just over 17 minutes, so you only have that much time to get everyone across and cut the ropes.?

Unfortunately, the bridge can only hold two people at a time.?

To make matters worse, it's so dark out that you can barely see, and the old lantern you grabbed on your way only illuminates a tiny area.

Can you figure out a way to have everyone escape in time?

教授計算出來僅僅在17分鐘之后，僵尸就會追上你們因此只有這么多時間 讓所有人過橋并剪斷繩索。

不幸的是，吊橋只能承載兩個人的重量。

更糟糕的是天昏地黑，眼前伸手不見五指，而你一路提著的燈只能照亮一小塊地方。

你能想出一個方案，讓所有人及時逃脫嗎？

Remember: no more than two people can cross the bridge together, anyone crossing must either hold the lantern or stay right next to it, and any of you can safely wait in the dark on either side of the gorge. Most importantly, everyone must be safely across before the zombies arrive. Otherwise, the first zombie could step on the bridge while people are still on it. Finally, there are no tricks to use here. You can't swing across, use the bridge as a raft, or befriend the zombies. Pause the video now if you want to figure it out for yourself!

請記?。旱鯓蛑荒艹休d兩個人的重量，任何人在橋上時必須 要么提著燈，要么緊挨著燈，任何人都可在峽谷兩側(cè)的黑暗中安全等待。最重要的是，所有人必須 在僵尸到達之前安全通過吊橋。否則，當(dāng)僵尸走上橋時，有人還在上面。最后，這里不能使用任何花招。不能蕩過去，不能把橋用作木筏，不能和僵尸做朋友。請馬上暫停視頻 如果你想自己尋找答案。

At first it might seem like no matter what you do, you're just a minute or two short of time, but there is a way.?

The key is to minimize the time wasted by the two slowest people by having them cross together.

And because you'll need to make a couple of return trips with the lantern, you'll want to have the fastest people available to do so.?

So, you and the lab assistant quickly run across with the lantern, though you have to slow down a bit to match her pace.

After two minutes, both of you are across, and you, as the quickest, run back with the lantern.

Only three minutes have passed.?

So far, so good.

起初似乎無論怎么安排都得超出一兩分鐘，但可行的方案是存在的。

最關(guān)鍵的想法是最小化最慢的兩個人所浪費的時間這可通過讓他們一起過橋來實現(xiàn)。

因為需要有人提著燈返回所以得讓速度最快的人來完成這個任務(wù)。

綜上，你和助理提著燈快跑過橋雖然你必須為她而放慢一點腳步。

但兩分鐘后，你倆都過橋了速度最快的你提著燈跑回去。

現(xiàn)在僅僅過了三分鐘。

目前為止，一切順利。

Now comes the hard part.

The professor and the janitor take the lantern and cross together.

This takes them ten minutes since the janitor has to slow down for the old professor who keeps muttering that he probably shouldn't have given the zombies night vision.?

By the time they're across, there are only four minutes left, and you're still stuck on the wrong side of the bridge.

現(xiàn)在最耗時的部分來了。

教授和門衛(wèi)接過燈一起過橋。

這用了他們十分鐘，因為門衛(wèi)必須為教授放慢腳步，教授嘴里咕噥著 也許當(dāng)初他不該給僵尸夜視能力。

當(dāng)他們過橋后，時間只剩下四分鐘，可你仍困在危險的一側(cè)。

But remember, the lab assistant has been waiting on the other side, and she's the second fastest of the group.

So she grabs the lantern from the professor and runs back across to you.?

Now with only two minutes left, the two of you make the final crossing.

As you step on the far side of the gorge, you cut the ropes and collapse the bridge behind you, just in the nick of time.?

Maybe next summer, you'll just stick to the library.

然而讓我們回憶一下 ，就會知道助理在另一側(cè)已經(jīng)等候多時了，她是一行人中第二快的。

所以她從門衛(wèi)手中接過燈跑過橋回到你那。

現(xiàn)在只剩兩分鐘，你倆最后一次過橋。

你一踏上峽谷的另一側(cè)就剪斷繩索，摧毀身后的吊橋，這樣時間剛好趕上。

或許，明年夏天，你只愿泡在圖書館里
