Emmett's Jeep
he drove his car as fast as he could and went to Alaska with tanya's family and stayed there until he calmed down!
Rosalie's red convertable or Emmetts jeep
He realized he loved her, and wanted to be closer to her. He asks he questions on their way to school, to get to know her.
He was in Alaska, trying to run away and get away from her as he couldn't help himself around her...to have a break reaally, so yeah he was in Alaska.
That depends on which book. In New Moon, it was more than 3 months; maybe 4.In Twilight, it was only a couple of days. There's also the fact he always ditches school on sunny days.
