it's true that my head is not in the right place. Thanks!

I may have lost my mind, but looking at the wall clock at 3:15 p.m., I see that both hands are pointing to the right, i.e. they overlap each other and point to the number 3. Thus, the smallest angle between the hands is 0. What I'm wrong about?

For example, the time is "15:15".
How can the angle be 7.5? It should be equal to 0.
The first test expects 7.5.

Thank you!
