Uniform angular velocity

2024 Re-NEET 1 question

1. Let $\omega_1,\omega_2$ and $\omega_3$ be the angular speed of the second hand, minute hand and hour hand of a smoothly running analog clock, respectively. If $x_1,x_2$ and $x_3$ are their respective angular distances in 1 minute then the factor which remains constant (k) is
