Far and away the best prize that life offers is the chance to work hard at work worth doing.

Figure 1: Position of the Sun in the Milky Way (Source).
I was reading Quora this week and I saw the following statement that mentioned the orbital speed of the Sun as it revolves about center of the Milky Way.
Earth revolves around the Sun at a speed of 30 km/s and our solar system revolves around the galactic center at 220 km/s.
The Sun's orbital speed about the Milky Way's galactic center is an interesting number and I thought it would be useful to compute this value here.
Figure 2 shows my analysis.
I consider 213 km/s close enough to 220 km/s to say that I understand the number I saw on Quora.
