P is a particle on the circle shown above. What is the length of the path traveled by P in one complete revolution around the circle?
(1) The diameter of the circle is 1.5 meters.
(2) The particle P moves in a clockwise direction at 0.5 meter per second.

Target question: What is the length of the path traveled by P in one complete revolution around the circle?
REPHRASED target question: What is the circumference of the circle?
Statement 1: The diameter of the circle is 1.5 meters.
Circumference = (π)(diameter)
So, the answer to the REPHRASED target question is the circumference = 1.5π meters
Since we can answer the target question with certainty, statement 1 is SUFFICIENT
Statement 2: The particle P moves in a clockwise direction at 0.5 meter per second.
Particle P's speed will NOT help us answer the REPHRASED target question with certainty
Statement 2 is NOT SUFFICIENT
Answer: A

The Logical approach to this question starts with the circumference formula, 2πr. So, in order to answer the question we need the length of the radius.
Statement (1) is enough on its own, since the radius is half the length of the diameter.
Statement (2) is not enough, as the speed in which the particle moves cannot tell us the length of the path it travels without knowing the time (distance = speed x time.
The correct answer is (A).
