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. 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. 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? 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! Answer in: 3 Answer in: 2 Answer in: 1 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. 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. 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.
Stažiranje u udaljenom laboratoriju na planini možda i nije bila najbolja ideja. Povlačenje poluge sa znakom lubanje samo iz znatiželje također nije bilo baš pametno, ali sad je kasno za plakanje jer moraš brzo pobjeći od mutantskih zombija. S tobom su domar, asistentica i stari profesor. U prednosti si, ali samo je jedan put do spasa: preko starog visećeg mosta iznad velike provalije. Ti možeš prijeći za jednu minutu, asistentica za dvije. Domar je sporiji i treba mu pet minuta, a profesoru treba čak deset minuta, jer se cijelim putem mora pridržavati za užad. Prema profesorovim izračunima, zombiji će vas stići za 17 minuta, pa imaš točno toliko vremena da svi prijeđu i da prerežeš užad. Nažalost, preko mosta može prelaziti samo dvoje ljudi odjednom. Da bi stvar bila još gora, vani je jako mračno i ništa se ne vidi, a stara lampa koju si dohvatio putem osvjetljava samo usko područje. Možeš li naći način da svi pobjegnu na vrijeme? Zapamti, preko mosta mogu prelaziti samo dvojica odjednom, onaj koji prelazi mora ili nositi lampu ili joj biti jako blizu i sigurni ste dok čekate u mraku na bilo kojoj strani provalije. I najvažnije: svi moraju prijeći na drugu stranu prije dolaska zombija. U protivnom, zombi bi mogao stati na most dok je na njemu još uvijek netko od vas. Ne možeš se služiti trikovima. Ne možeš se zaljuljati preko mosta, koristiti most kao splav, ili se sprijateljiti sa zombijima. Ako želiš sam doći do rješenja, pauziraj video! Odgovor za: 3 Odgovor za: 2 Odgovor za: 1 Isprva se čini da bez obzira što uradio nedostaje ti minuta ili dvije, ali postoji rješenje. Treba minimizirati vrijeme koje se potroši na dvoje najsporijih tako da prijeđu zajedno. Nekoliko puta ćeš se morati vraćati s lampom pa za to trebaš najbrže ljude. Dakle, asistentica i ti brzo pretrčite preko mosta s lampom iako moraš usporiti jer je ona sporija. Nakon dvije minute oboje ste prešli a ti se vratiš natrag s lampom jer si najbrži. Prošle su samo tri minute. Za sad je dobro! Sada dolazi teži dio. Profesor i domar uzimaju lampu i prelaze zajedno. Za to im treba deset minuta jer domar mora usporiti zbog starog profesora koji mrmlja putem da nije trebao zombijima dati noćni vid. Kad njih dvojica prijeđu, ostaju ti još četiri minute, a ti si i dalje na krivoj strani mosta. Ali nemoj zaboraviti, asistentica čeka na drugoj strani, a ona je druga najbrža u grupi. Asistentica uzima lampu od profesora i otrči natrag po tebe. Ostale su još dvije minute, i vas dvoje prelazite most zadnji put. Kad kročite na suprotnu stranu, prerežete užad i most iza vas se uruši, u posljednjem trenutku. Slijedećeg ljeta možda bi se trebao držati knjižnice.
