What is the angular speed (in rev/min) of the Earth as it orbits about the Sun?

Earth makes 1 complete revolution around the Sun after approximately 365 days. The angular speed in rev/min may be determined by using dimensional analysis and conversion factors.

(1 rev/365 days) x (1 day / 24 hours) x (1 hour / 60 mins) = 1.90 x 10^-6 rev/min

Therefore, Earth's angular speed is approximately 1.90x10^-6 rev/min.
