To determine the time in Nigeria when it is noon in London, we need to consider the time difference between the two locations. The time difference is based on the concept of time zones and is typically measured in terms of the number of hours ahead or behind Greenwich Mean Time (GMT).

Since London is located at longitude 0 degrees, it falls within the GMT time zone. Nigeria, on the other hand, is located at approximately longitude 50 degrees west, which means it is 50 degrees west of GMT.

Every 15 degrees of longitude represents a time zone change of one hour. Therefore, to calculate the time difference between Nigeria and London, we divide 50 degrees by 15 degrees per hour. This gives us approximately 3 hours and 20 minutes.

Since London is in the GMT time zone, when it is noon there, Nigeria will be 3 hours and 20 minutes behind. Therefore, in Nigeria, it would be 8:40 AM when it is noon in London.

Please note that this calculation is based on the assumption that both London and Nigeria observe standard time without considering daylight saving time changes, which may affect the time difference during certain periods of the year.
