The angle between the hands at 7:20

At 7:20 on an ordinary analogue clock, what is the angle between the hour hand and the minute hand? Give the smaller of the two angles, in degrees.

The trap: many people put the hour hand exactly on the 7. It is not there.

Show a hint

The minute hand moves 6 degrees per minute. The hour hand moves 30 degrees per hour, which is half a degree per minute.
