Question 1669Navigation General

The correct answer is A) departure. The distance between any two meridians measured along a parallel of latitude and expressed in miles is called the departure. This is because the distance between meridians decreases as you move away from the equator, and the departure represents the east-west distance traveled along a parallel of latitude. The other options are incorrect because: B) meridian angle refers to the angle between two meridians, not the distance between them. C) difference in longitude refers to the angular difference between two meridians, not the distance between them. D) mid-longitude is the average longitude between two points, not the distance between meridians.
