Question

Question 7 (d)

Where will the hour hand of a clock stop if it starts:
from 7 and turns through 2 straight angles?

Answer 1

A complete revolution of the hour hand covers 12 hours or four right angles or two straight angles i.e ${360}^{\circ }$.
Which means 1 hour = ${30}^{\circ }$.
We know two straight angles = ${360}^{\circ }$.
And ${360}^{\circ }$ = 12 hours
12 hours in a clockwise direction from 7, the hour hand will return to 7.
