At which longitude would the local time be 6 hours ahead of GMT?

At which longitude would the local time be 6 hours ahead of GMT?

Step 1: Understand that GMT (Greenwich Mean Time) is the time at the Prime Meridian, which is at 0° longitude.
Step 2: Know that the Earth is divided into 360 degrees of longitude.
Step 3: Realize that the Earth rotates 360 degrees in 24 hours.
Step 4: Calculate how many degrees correspond to one hour of time: 360 degrees / 24 hours = 15 degrees per hour.
Step 5: Since we want to find the longitude that is 6 hours ahead of GMT, multiply 6 hours by 15 degrees per hour: 6 * 15 = 90 degrees.
Step 6: Determine the direction: 90 degrees east of the Prime Meridian is 90°E.

Longitude and Time Zones – Understanding how longitude affects local time, where each 15° of longitude corresponds to a one-hour difference from GMT.
GMT and Local Time Calculation – Calculating local time based on the difference from Greenwich Mean Time (GMT) using the formula: hours ahead or behind * 15°.
