Question: how to calculate time in geography?
Answer: A full circle rotation of the earth on its axis towards and then away from the sun equals one day, or 24 hours. If a full rotation in time = 24 hours and a full rotation in degrees = 360, then 24 hours = 360 degs. This also means that one hour = 360 degs ÷ 24, which = 15 degs.
