Answer:
If I flew over Mt. Everest and then over the Nile River, I would be traveling west.
Explanation:
Mount Everest is located in the Himalayas, on the border between Nepal and the People's Republic of China. Its exact location is at 27° 59′ 17″ N 86° 55′ 31″ E.
In turn, the mouth of the Nile River is at the southeast end of the Mediterranean Sea, in Egypt. Its exact location is variable: that of Rosetta, the closest city to its mouth is 31° 24′ 05″ N 30° 25′ 10″ E, while that of Jinja, near its birth in Lake Victoria, is located at 0° 25′ 28″ N 33° 12′ 15″ E.
Therefore, starting from Everest, to reach the Nile you can travel both to the northwest and southwest, so the only correct statement is that the trip is being made to the west.
