Question

Where will the hand of a clock stop if it

(a) Starts at 12 and makes of a revolution, clockwise?

(b) Starts at 2 and makes of a revolution, clockwise?

(c) Starts at 5 and makes of a revolution, clockwise?

(d) Starts at 5 and makes of a revolution, clockwise?

Answer 1

In 1 complete clockwise revolution, the hand of a clock will rotate by 360º.

(a) If the hand of the clock starts at 12 and makes of a revolution clockwise, then it will rotate by 180º and hence, it will stop at 6.

​​

(b) If the hand of the clock starts at 2 and makes of a revolution clockwise, then it will rotate by 180º and hence, it will stop at 8.

(c) If the hand of the clock starts at 5 and makes of a revolution clockwise, then it will rotate by 90º and hence, it will stop at 8.

(d) If the hand of the clock starts at 5 and makes of a revolution clockwise, then it will rotate by 270º and hence, it will stop at 2.
