To find the total air distance from Port Said, Suez Canal, Egypt to Capetown, South Africa, and then to Zanzibar City, Tanzania, we need to add up the individual distances.
First, we find the distance from Port Said, Suez Canal, Egypt to Capetown, South Africa, which is 4,590 miles according to the table.
Next, we find the distance from Capetown, South Africa to Zanzibar City, Tanzania, which is 2,350 miles according to the table.
To find the total air distance, we add these two distances together: 4,590 miles + 2,350 miles = 6,940 miles.
Therefore, the total air distance from Port Said, Suez Canal, Egypt to Capetown, South Africa, and then to Zanzibar City, Tanzania is 6,940 miles.
