Figure-eight symmetry on clocks and watches

Of course, eyebrows are symmetrical, so the hour hand and the minute hand are equidistant from the center line, that is, six places.

Suppose it should be 8: 00 x, then

30-x=(40-30)+x/ 12

Multiply both sides by 12.

360- 12x= 120+x

13x=240

X=240/ 13= 18 and 6/ 13.

Answer: It should be 8: 00, 18, 6/ 13.
