Answer:
Step-by-step explanation:
To determine the location of a ship when the Sun is at the highest position in the sky (noon), we need to use a process called celestial navigation. This involves measuring the altitude of the Sun above the horizon at local noon, and then using this information to calculate the ship's latitude and longitude.
Assuming that we have the necessary instruments and data, the process would look something like this:
Time 13:00 in Greenwich, England (1 PM)
Assuming that the ship is located in a time zone that is 3 hours behind Greenwich (such as the eastern coast of the United States), local noon would occur at 10:00 AM. The navigator would measure the altitude of the Sun at this time, and then use a table or formula to calculate the ship's latitude and longitude based on this measurement and the current date.
Time 10:00 in Greenwich, England (10 AM)
Assuming that the ship is located in a time zone that is 2 hours ahead of Greenwich (such as Greece or Turkey), local noon would occur at 12:00 PM. The navigator would measure the altitude of the Sun at this time, and then use a table or formula to calculate the ship's latitude and longitude based on this measurement and the current date.
Midnight (24:00) or 12:00 AM
At midnight, the Sun is not visible and therefore celestial navigation cannot be used to determine the ship's location. However, other methods such as dead reckoning or GPS may still be used to estimate the ship's position.
Noon (12:00) or 12:00 PM
Assuming that the ship is located in a time zone that is the same as Greenwich (such as the United Kingdom), local noon would occur at 12:00 PM. The navigator would measure the altitude of the Sun at this time, and then use a table or formula to calculate the ship's latitude and longitude based on this measurement and the current date.
