Answer 2

The Geographical Longitude of the Island

To determine the geographical longitude of the island, we need to consider the time shown on the sundial when the ship reached the shores of the island. In this case, the sundial showed 13:00 (1:00 PM).

The geographical longitude can be calculated by converting the time difference between the ship's location (London) and the island into degrees. Since the sundial in London shows the local solar time, we need to convert it to the standard time (Greenwich Mean Time - GMT) before calculating the longitude.

To calculate the geographical longitude, we can use the following formula:

Longitude = (Time difference / 24 hours) * 360 degrees

Let's calculate the geographical longitude of the island using the given information.

Calculation:

1. Convert the local solar time to GMT: - London is located in the Western European Time Zone (WET), which is GMT+0. - The sundial in London showed 13:00 (1:00 PM). - Since London is in the GMT+0 time zone, the local solar time is already in GMT.

2. Calculate the time difference between London and the island: - The sundial in London showed 13:00 (1:00 PM). - The ship reached the shores of the island at the same time. - Therefore, there is no time difference between London and the island.

3. Calculate the geographical longitude: - Since there is no time difference, the time difference in hours is 0. - Using the formula: Longitude = (0 / 24) * 360 = 0 degrees

Conclusion:

Based on the given information, the geographical longitude of the island is 0 degrees.

Unfortunately, without additional information, it is not possible to determine the specific island based solely on its geographical longitude.
