The question of distance between two straight lines arises only when they are parallel. The given lines are parallel. If the equations of parallel lines are ax + by + c = 0 and ax + by + c' = 0, then the perpendicular distance between them is given by. p = l c - c' l / sqrt ( a^2 + b^2 )
Find the distance between two cities in miles and kilometers for flying or driving distance. You can drag and drop the map marker to the location where you want to calculate the distance between. â The red line on the map indicates the Great Circle Distance. â The black line is the Rhumb line between the two points.
