Answer the following questions. Provide the full answers. 5. What were the challenges in keeping accurate time at sea and why was the lunar- distance method believed to be the only viable solution for finding longitude? [1]​

Ответ:The challenges in keeping accurate time at sea were mainly due to the motion of the ship, changes in temperature and humidity, and the lack of reliable timekeeping devices. Traditional methods of timekeeping, such as using a sundial or an hourglass, were not suitable for use on a moving ship.

The lunar-distance method was believed to be the only viable solution for finding longitude because it relied on celestial observations rather than accurate timekeeping. By measuring the angular distance between the moon and a known star, sailors could calculate their longitude. This method did not require precise timekeeping, as long as the observations were made accurately. It was considered more reliable than other methods, such as using a chronometer, which could be affected by the ship's motion and other factors.
