Answer 2

Calculation of Day Length on October 7th

To determine the duration of the day on October 7th, we can set up an equation based on the given information. Let's assume that the original duration of the day on October 7th is represented by x hours.

According to the information provided, the duration of the day from October 7th to November 19th decreased by 3 hours and became 8 hours. We can express this as:

x - 3 = 8

To find the value of x, we can solve this equation:

x - 3 = 8

Adding 3 to both sides of the equation:

x = 11

Therefore, the original duration of the day on October 7th was 11 hours.

Please note that the search results did not provide specific information about the duration of the day on October 7th. The calculation was based solely on the given information and the equation provided.
