Crossy Bridge

You are in the lab of a scientist. You accidentally push a random button and BOOM! Lots and lots of zombies got out. You, the assistant, another assistant (but older) and the scientist tried to run. You were trapped and the only way to safety is a very old bridge. You and the others have to get to the other side, cut the strings and you're safe. According to the scientist, the zombies would be close to you for almost 17 minutes. You can get across the bridge for takes minute, the young assistant 2 minutes, the assistant ( older ) takes 5 minutes but the scientist takes........10 minutes. You have to get everyone across, but in time, because if you are on the bridge but the zombies are there, YOU FAILDED!!!! Besides, to get there, you need a lantern. Someone who got there can grab the lantern can come back and grab another, and the others can wait. The lantern can only shine for 2, so think hard.

Who would be the first ones to across? (that includes you)
