Answer:
Every four minutes, the earth has turned one degree. In one minute of time, the earth has turned 15 minutes of arc. So, every four seconds of time, the earth rotates one minute of arc. Each of the infinite meridians has a different time as its position relative to the sun changes during the rotation.
hope it helps

Time taken to rotate 1 time: 1 day
1 day: 24 hours or 1440 minutes.
Degrees turned in one rotation: 360 degrees
Time taken to turn 1 degree longitude: 1440/360 = 4 minutes
