The earth requires 24 hours for one rotation. In one hour, ______.
Options
5 longitudes will face the sun
10 longitudes will face the sun
15 longitudes will face the sun
20 longitudes will face the sun
Solution
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°
