उत्तर
The earth requires 24 hours for one rotation. In one hour, 15 longitudes will face the sun.
Explanation:
Longitude is the angular distance of a place east or west of the meridian at Greenwich, England. It is represented in degrees.
One rotation = 360°
The time required for the earth to complete one rotation = 24 hours
Therefore, longitudes covered in one hour = `360/24` = 15°
