Question

5. What fraction of revolution does the hour hand of
a clock turn through when it goes from
(a) 9 to 6
(b) 3 to 6 (c) 5 to 8
(d) 2 to 11 (e) 8 to 11 ?​

Answer 1

Answer:

This is 180°/360° = ½ of the complete revolution. When the hour hand of a clock moves from 12 to 3, from 3 to 6, from 6 to 9 and from 9 to 12, it makes a right angle. So, when the hour hand of a clock turns four right angles, it is said to make a complete revolution, 360°.
