The earth rotates 7/25 of mile every second the earth is 2/5 of mile away from completing. A fullrotation
To find out how long it takes for the Earth to complete a full rotation, we need to divide the remaining distance by the distance covered per second.
The distance covered per second is 7/25 of a mile.
The remaining distance is 2/5 of a mile.
So the time it takes for a full rotation is:
(2/5) / (7/25) = (2/5) * (25/7) = (2/1) * (5/7) = 10/7 = 1 3/7
Therefore, it takes 1 3/7 seconds for the Earth to complete a full rotation.
