There are several possible answers to this question. The angular rate is 360 degrees in a month, or about 12 degrees a day. This gives about half a degree of movement per hour.
If you want the velocity of the moon in its orbit, use the fact that the radius of the moon's orbit is 238,000 miles; multiply it by 2pi to get the circumference and divide that by 30*24=720 hours per month to get an approximate value of 2100 miles per hour.

An approximate value for the rate at which the moon orbits the earth is one orbit per month. Month is from AS monath; akin to mona or moon (Webster). Strange how we lose the original clear connection between a word and its meaning, right?

"The Moon makes a complete orbit about the Earth approximately once every 27.3 days."

Speed = Distance traveled / Time
Circular Distance = Pi x Diameter
Earth-Moon Radius = 230,000 miles; Diameter = 460,000 mi.
Distance = 3.14 x 460,000 = 1,445,000 miles
Time = 27.3 days (from an earlier answer)
= 27.3 days x 24 hours/day = 655 hours
Speed = Distance/Time = 1,445,000/655 = 2206 mph

The moons orbital velocity is approximately 2,300 mph (3,700 kph).
