Answer:
The answer to the question is
30 ° east of Greenwich Mean Time
Step-by-step explanation:
To solve this we have the given variables
Current Greenwich Mean Time = 10.00 AM
Location of the Sun at the current longitude = zenith
Supposed correct time when clock is at zenith = 12 noon or 12.00 pm
Time difference, or correction required = 10.00 a. m. - 12 p. m. = 2 hours leading
As there are 24 hours in a day one hour of the difference in time is equivalent to 360/24 or 15 ° and as the Sun is already at its zenith at the location then the location is eastwards of Greenwich Mean time that is,
15 ° × 2 = 30 ° east of Greenwich Mean Time
