Angular velocity of the minute hand

Question

The exercise is to calculate the angular velocity (in radians per hour) of the rotation of:

1. the hour hand, and

2. the minute hand (of the clock).

Neither of my answers coincides with the answers in the book:

1. (after corrections) The hour hand goes $30$° in an hour, so the answer I get is $\color{red}{\pi \over 6}$ rad/hour, but the book has $\color{blue}{2\pi}$ rad/hour.

2. (after corrections) The minute hand goes $360$° in an hour, so the answer I get is $\color{red}{2\pi}$ rad/hour, but the book has $\color{blue}{\pi \over 30}$ rad/hour.

Thank you for all your comments so far. I guess the question is now: are the red ones right or the blue ones? I no longer know what's going on with this textbook.
