What is the measure of the angle swept out by the second hand if it starts on the 3 and continues for 3 minutes and 20 seconds?

Answer 1

For the 3 minutes that would be 3 times around back to the 3 or 3×360° = 1080°.

For the 20 seconds that would be (20/60) × 360° = 120°.

The total will be 1080°+120° = 1200°.
