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).
Hopping up on their hind legs like a kangaroo, they can â¦reach speeds of 64 km. per hour. The hare can swim across narrow streams. Arctic hares are fast and can bound at speeds of up to 40 miles (60 kilometres) an hour, because of the bone structure and their long limbs, they are able to do this. If you look at the hind limbs they are bent as if crouched down.
