Find the shortest distance between the lines whose vector equations are
The given lines are
and ![]()
It is known that the shortest distance between the lines,
and
, is given by,

Comparing the given equations with
and
, we obtain 


Substituting all the values in equation (1), we obtain
![]()
Therefore, the shortest distance between the two given lines is
units.
