Physical quantities are measured as 'nu' where n is the magnitude and u is the unit. For example: A boy measured the length of a room as 3 m. Here 3 is the magnitude and m (metre) is the unit. 3 m can also be written as 300 cm.
No. The only European units I know of who were able to sustain that. kind of speed on foot were Foreign Legion-where the standard was 50. km per day. Other infantry units usually come in under 20 miles a day. (and closer to 12-15 miles per day).
The moon orbits Earth at an avaerage speed of 2,288 miles per hour (3,683 kilometres per hour). The Moon travels at different speeds during different parts of its orbit. It moves slowest when it is at furthest distance from Earth. The Moon moves fastest in its orbit when it is closest to Earth.
