What is the angle between the hands of a clock at 6:30?

Explanation

In one hour, the minute hand covers 360∘ and the hour hand covers 30∘.

When the minute hand covers 180∘, the hour hand covers 15∘.

So at 6:30, the minute hand covers 180∘ , and the hour hand covers 195∘.

The angle included between the minute and hour hand at 6:30 is 15∘.
