If the starting place is the airport,
then after moving 9 units to the right , you will reach (4, 5). Then, moving 6 units upward, you will reach (4, 10). But, the stadium is at (5, 3).
If the starting place is the chocolate factory, after moving 9 units to the right, you will reach (5, 3). Then, moving 6 units upward, we will reach (5, 3).
The stadium is at the same coordinates(5, 3).
Hence, the chocolate factory is your starting place.
