Aero Center / Map Practice Test

In a circular mileage layout around a city, “second mileage clockwise from Sidon” means you start at Sidon and move around the circle in the clockwise direction, counting each mile marker you encounter. The first marker you meet is 23 miles in the northeast direction, and the next one you reach is 24 miles in the northwest direction. That makes the second mileage clockwise from Sidon the 24 miles NW. The other options would appear later in the clockwise sequence, so they’re not the second marker.
