The Nile is the world’s longest river, 4,160 miles. Consider the southern boundary of Ancient Egypt to be at Aswan (the first cataract, or rapids). About how many miles of the Nile are actually in Egypt?

Answer 1

If the southern boundary of Ancient Egypt is at Aswan, then the distance of the Nile within Egypt would be the difference between the total length of the Nile and the distance from Aswan to the Mediterranean Sea.

The distance from Aswan to the Mediterranean Sea is approximately 800 miles.

Therefore, the approximate number of miles of the Nile within Egypt would be 4,160 miles - 800 miles = 3,360 miles.
