be the value of its prime meridian? Show through calculation.

​

Answer 1

The value of the prime meridian for a country whose standard time is three hours ahead of Greenwich Time is 45 degrees east.

Calculating the values of prime meridian:

The prime meridian is the line of longitude that has a value of 0°. It passes through the Royal Observatory in Greenwich, London, England.

If the standard time of a country is 3 hours ahead of Greenwich Mean Time (GMT), it means that the country is located three time zones to the east of the Greenwich Meridian.

Here each time zone is equal to 15 degrees of longitude. Therefore, if a country is 3 time zones to the east of Greenwich,

it can be calculated as 3 x 15 = 45° to the east of the Prime Meridian.

Since the Prime Meridian has a longitude of 0°, the longitude of this country's prime meridian would be 0 + 45 = 45° E.

Therefore,

The value of the prime meridian for a country whose standard time is three hours ahead of Greenwich Time is 45° E.

Answer 2

Answer:

The value of the prime meridian for a country that is three hours ahead of GMT would be the longitude of the country minus 45 degrees.

Explanation:

From the above question,

The top meridian is the line of longitude that has a price of zero degrees. It passes via the Royal Observatory in Greenwich, London, as a result the time period Greenwich Time or GMT.

If a country's general time is three hours beforehand of GMT, it skill that they are at a longitude that is three hours in advance of the high meridian. Since the Earth rotates 360 tiers in 24 hours, it rotates 15 tiers in one hour (360/24 = 15). Therefore, a time distinction of three hours corresponds to a longitude distinction of three x 15 = 45 degrees.

To discover the price of the high meridian for a usa that is three hours in advance of GMT, we want to subtract forty five levels from the longitude of the country. For example, if a country's longitude is 60 levels East, its high meridian would be at 60 - forty five = 15 levels East.

So the fee of the top meridian for a united states of america that is three hours beforehand of GMT would be the longitude of the united states minus forty five degrees.
