Distance, or farness, is a numerical description of how far apart objects are. In physics
or everyday usage, distance may refer to a physical length, or an
estimation based on other criteria (e.g. "two counties over"). In mathematics, a distance function or metric
is a generalization of the concept of physical distance. A metric is a
function that behaves according to a specific set of rules, and is a
concrete way of describing what it means for elements of some space to
be "close to" or "far away from" each other. In most cases, "distance
from A to B" is interchangeable with "distance between B and A".
Distance is a scalar quantity . It has only magnitude not direction . Distance is a very fundamental unit .
Example of distance - distance between hodal and delhi is 90 km ,distance of faridabad from hodal is70 km , etc
