Explanation:

The Suez Canal is an ocean level conduit in Egypt, associating the Mediterranean Sea to the Red Sea through the Isthmus of Suez. Developed by the Suez Canal Company somewhere in the range of 1859 and 1869, it was authoritatively opened on 17 November 1869. The waterway offers watercraft a more straightforward course between the North Atlantic and northern Indian seas by means of the Mediterranean and Red oceans, therefore maintaining a strategic distance from the South Atlantic and southern Indian seas and in this way lessening the voyage separate from the Arabian Sea to, for instance, London by roughly 8,900 kilometers (5,500 mi). It extends from the northern end of Port Said toward the southern end of Port Tewfik at the city of Suez.
