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. â The blue line indicates the driving distance route. Distance calculator helps you to find how many miles from a city to an another city on map. Distance between cities or 2 locations are measured in both kilometers, miles and nautical miles at the same time. Air distance is the bird fly distance between two locations which is calculated with the great circle formula.
