This one's for Mr. Inch- Mathematics at sea on the Costa Mediterranea

The nautical mile = 1852m
Our Itinerary on the Costa Mediterranea.
Savona - Civitavecchia = 205 nautical miles
Civitavecchia - Mykonos = 820 nautical miles
Mykonos - Izmir = 143 nautical miles
Izmir - Istanbul = 282 nautical miles
Istanbul - Constanza = 191 nautical miles
Constanza - Odessa = 205 nautical miles
Odessa - Yalta = 217 nautical miles
Yalta - Piraeus = 676 nautical miles
Piraeus - Katakolon - 237 nautical miles
Katakalon - Savona- 787 nautical miles
We sailed a total of 3763 nautical miles in 13 days, to see 5 different countries.
The nautical mile
the exact length of the measurement became an issue for sailors in the early 1600's when they needed to learn how to use the new charts and develop their abilities in trgonometry. During this period they tried to measure with precision the length of a latitude degree. the Englishman Richard Norwood who had also invented the broken Rumble Line obtained a measure very close to reality. As a resuult of these measurements and a more accurate determination of the Earth's real dimensions they decided to adopt a mile that would measure more than the land or "Roman" mile which had been used to determine distances at sea, calling it the "long Mile" In 1730 it received the name nuatical mile but it was not until 1929 when it was accepted as the international nautical mile measuring 1852 m.

Now I just have to estimate how many kilograms of pizza and gelato I consumed.
