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).
When on land, the Australian freshwater crocodile can âgallopâ up to 11 miles per hour (mph). But most crocodiles use a kind of âbelly run,â which can move them seven to 10 mph. And even if its prey stays out of the water, crocodiles can suddenly leap from the depths at speeds up to 30 mph, snatch an animal with its jaws and drag it under water! Theyâve got plenty of big, sharp teeth as well.
