1. **Problem Statement:** Determine the best location of St Vincent on the given grid map using latitude and longitude coordinates. 2. **Understanding the Map:** The x-axis represents longitude degrees from 50° to 60° (left to right). The y-axis represents latitude degrees from 10 to 15 (top to bottom). 3. **Given Data:** The position of Dominica is approximately at longitude 61° and latitude 15° (from the context). The problem states a location 0.1 degrees east and 2.9 degrees south of Dominica. 4. **Calculating Coordinates:** - Longitude of St Vincent = Longitude of Dominica + 0.1 degrees east - Latitude of St Vincent = Latitude of Dominica - 2.9 degrees south 5. **Substitute values:** - Longitude of St Vincent = 61 + 0.1 = 61.1° - Latitude of St Vincent = 15 - 2.9 = 12.1° 6. **Interpretation:** St Vincent is located at approximately longitude 61.1° and latitude 12.1° on the map. 7. **Conclusion:** The best location of St Vincent on the grid map is at coordinates (61.1°, 12.1°).
