Mila [183]

Distance between the two cities is 26 meters.

12 centimeters on the map is equivalent to 120 meters on the ground.

First thing to do is to find out the distance on the ground that 1 cm on the map represents:

= 120 / 12

= 10 meter

1cm on the map is 10 meters on the ground.

If the distance on the map is 2.6 cm, on ground it will be:

= distance on map x conversion factor

= 2.6 x 10

= 26 meters

Distance between the two cities is 26 meters.

Note: check to see if the question said kilometers or miles instead of meters.
