On a map with a scale of 1: 500000, the distance between cities is 1.9 m, find the distance on the ground.

Most likely the distance on the map is 1.9 cm.

In this case, when converting the scale of the map from centimeters to kilometers, its value will be:

500000/100000 = 5 km in 1 cm.

To find the distance on the ground, we multiply the distance on the map by the map scale in kilometers.

As a result, we get:

1.9 * 5 = 9.5 km.

If the segment length is 1.9 m, then the distance on the ground will be:

1.9 * 100 * 5 = 190 * 5 = 950 km.

Answer: Distance on the ground is 9.5 km.
