     Calculate cargo plane travel time between two coordinates using the great-circle distance.
 
     Args:
-        origin_coords (Tuple[float, float]): Latitude and longitude of the starting point (e.g., (42.3601, -71.0589)).
-        destination_coords (Tuple[float, float]): Latitude and longitude of the destination (e.g., (40.7128, -74.0060)).
-        cruising_speed_kmh (float): Speed of the cargo plane in kilometers per hour (default: 750.0).
+        origin_coords (Tuple[float, float]): The latitude and longitude of the starting point in degrees, e.g., (42.3601, -71.0589).
+        destination_coords (Tuple[float, float]): The latitude and longitude of the destination in degrees, e.g., (40.7128, -74.0060).
+        cruising_speed_kmh (float, optional): The cruising speed of the cargo plane in kilometers per hour. Defaults to 750.0.
