The Radius of the moon = 382 000 000 metres
Pi = 3.14159265
2 x 382 000 000 x 3.14159265 = 2 400 176784.6
The distance the moon travels in one revolution of the Earth is = 2 400 176784.6 meters
The moon takes 27.32166 days to orbit the Earth.
2 400 176 784.6 / 27.32166 = 87 848 863.67 (2dp) metres in one day.
87 848 863.67 / 24 = 3 660 369.32 (2dp) metres in one hour
3 660 369.32 / 60 = 61 006.16 (2dp) metres in one minute
61 006.16 / 60 = 1 016.77 (2dp) metres in one second
