The Tethys Ocean was an ocean that was situated between the European and African continents, through what is now the Middle East and parts of Central Asia, and the northern half of the Indian Ocean. Because of the geologic activities, mainly the movement of the Indian plate towards Asia, and the Alpine orogenesis, the ocean was becoming smaller and smaller, and it started to be divided into smaller pieces, until it totally disappeared.

We divide 400 between the 8 hours to obtain. 50 meters of distance advance in a single hour. Therefore in 4 hours and 25 minutes, it will be at the correct distance to be reached out and used.
