Answer 2

Calculating Local Time Difference

To calculate the local time difference between Kiev and Lviv, we can use the longitude difference between the two cities. The formula to calculate the time difference based on longitude is to divide the longitude difference by 15 (since the Earth completes one full rotation every 24 hours, and there are 24 hours in a day, so 360 degrees / 24 hours = 15 degrees per hour).

Given: - Kiev's longitude: 31° E - Lviv's longitude: 24° E

The longitude difference between Kiev and Lviv is 31° - 24° = 7°.

Using the formula, the time difference between Kiev and Lviv is 7° / 15° per hour = 0.47 hours, which is approximately 28 minutes.

Calculating Local Time in Lviv

Given that the local time in Kiev is 21:38, we can calculate the local time in Lviv by subtracting the time difference.

21:38 - 28 minutes = 21:10

Therefore, if the local time in Kiev is 21:38, then the local time in Lviv is 21 hours 10 minutes (option A).
