Plz I need one question about the longitude and latitude

Here's a question about longitude and latitude: A ship is located at coordinates 30° N latitude and 45° E longitude. If the ship travels 15° directly south, what is its new latitude? Solution: Step 1: Understand that latitude measures the angular distance, north or south, from the Earth's equator. North latitudes are positive, and south latitudes are negative. Step 2: The ship starts at 30° N latitude. Traveling directly south means decreasing the latitude value. Step 3: Subtract the distance traveled south from the initial latitude: 30° N - 15° = 15°. Step 4: Since the result is positive, the new latitude is north of the equator. The ship's new latitude is 15° N. Got more? Send 'em.
