Answer:
Matter is anything that takes up space. All matter (aka everything) is made up of atoms. The air that we breathe is matter because it is made up of mainly oxygen atoms, but also other atoms as well. The air also takes up what we would call free space. A wooden desk is matter because it takes up space and is made of oxygen, carbon, nitrogen, calcium, and several other elements and atoms.

It takes 30 minutes.
It rotates (360/30) = 12 degrees every minute.
In 12 minutes, 1 seat will rotate (12 x 12) = 144 degrees.
============================================
A slightly different way to do it:
1 rotation = 360 degrees
It takes 30 minutes.
12 minutes = (12/30) = 0.4 of a complete rotation.
0.4 of 360 degrees = (0.4 x 360) = 144 degrees
============================================
A slightly different way to do it:
Set up the proportion:
(30 minutes / 360 degrees) = (12 minutes / 'x' degrees)
Cross-multiply the proportion:
30 x degrees-minutes = (12 x 360) degree-minutes
Divide each side by '30 minutes':
'x' degrees = (12 x 360 degree minutes) / 30 minutes = 144 degrees
12minutes times 12 degrees equals 144 degrees.
