Question

why the countries like USA and russia have adopted more than one standard time????

Answer 1

This is because as the the area they cover is so big and the longitudes pass through them are more than one so they have more than one standard time.

Answer 2

Answer:

The countries like USA and Russia have adopted more than one standard time due to their great longitudinal extent.

Explanation:

• The local time of different locations have different meridian values.
• Therefore, it is essential to embrace the local time of some country's central meridian as the normal uniformity time for the nation.

• In India, 82°C (82°30'E) longitude is regarded as the normal meridian and the local time at that meridian is deemed the standard time for the entire nation. It is referred to as the Indian Standard Time (IST).

• Similarly, owing to their large longitudinal extent, some nations have embraced more than one standard time.
• There are as many as eleven normal times in Russia, for instance. The earth was split into twenty-four one-hour time zones.
