Answer 1

In half hour the long hand of a clock rotate through a angle of 180 degree

Answer 2

In ½ hour, the long hand of a clock rotate through an angle of 180°.

Explanation:

We must know that, the long hand of a clock represents the minutes hand.

In a clock, the total angle is 360 degrees.

Total time = 60 minutes.

In 1 minute, the minutes hand rotates through $\dfrac{360}{60}$ degrees = 6 degrees.

Also, ½ hour = 30 minutes and thus in 30 minutes, the minutes hand rotates through (30 × 6) degrees = 180 degrees.
