Mexico is a part of North America [1]. What is less obvious is whether Guatemala, Belize, Nicaragua, etc, would fall into N or S America. Central America is a region, like the Middle East, but is not its own continent. Central America is a part of North America [2]. Nathan made a good point that the United Nations considers Mexico a part of Central America [3]. I wonder why [4].
Sear each side, flipping minimally. It should not take long for a crisp brown crust to form. Depending on the heat of your pan, it should take about 2-4 minutes (or less) for each side to finish cooking. When the first side is done, flip your steak and cook the second side for about as long.
When hot, sear both sides of the steaks for 2-3 minutes. Sear close to the final color you want. Transfer pan to the preheated oven. Now comes the variables. The steak thickness, how long you seared and the true temperature of the oven. Cook to the final temperature you want.
