Answer:
Option D. 720°
Explanation:
In every rotation of a circle angle formed at the center is 360°. Therefore, in a clock which is in the form of a circle, angle formed by two rotations at the center will be 360×2 = 720°
Now question is whether the angle is positive or negative?
Angles are always measured counterclockwise, means angles measured counterclockwise are positive and measured clockwise are negative.
Therefore, 2 rotations counterclockwise is equal to 720°.
Option D. 720° is the answer.
