Question

Q7. Where will the hour hand of a clock stop if it starts

(a) From 6 and turns through 1 right angle?

(b) From 8 and turns through 2 right angles?

(c) From 10 and turns through 3 right angles?

(d) From 7 and turns through 2 straight angles?

Answer 1

In 1 complete revolution (clockwise or anti-clockwise), the hour hand of a clock will rotate by 360º or 4 right angles.

1. If the hour hand of a clock starts from 6 and turns through 1 right angle, then it will stop at 9.

2. If the hour hand of a clock starts from 8 and turns through 2 right angles, then it will stop at 2.

3. If the hour hand of a clock starts from 10 and turns through 3 right angles, then it will stop at 7.

4. If the hour hand of a clock starts from 7 and turns through 2 straight angles, then it will stop at 7.
