Two roman ships sail from rome at the same time, one to antioch and the other to london. all things being equal, which will arrive first?

The ship heading for Antioch.

Explanation:

Londinium was the Roman name for modern day London. It is located to the southeast of the British isles. Antioch was a Greek city located on what is today the southern coast of Turkey, near Lebanon. A ship departing from Rome would have to cover a distance of around 4,000 km. to London. The the ship heading for Antioch will arrive first, as it will have to cover only 2,300 km.
