Question

Where will the hour hand of a clock stop if it starts from 6 and turns through 1 right angle?

Answer 1

A complete revolution of the hour hand covers 12 hours or four right angles i.e ${360}^{\circ }$.
Which means 1 hour = ${30}^{\circ }$.
3 hours in a clockwise direction from 6 = 6 + 3 = 9
Hence, the hour hand will stop at 9.
