Calculate the ground distance between two places of the map distance is five centimetres?

To calculate the ground distance between two places on a map, you need to know the scale of the map.

If the distance of 5 centimeters on the map represents 50 kilometers in real life, you can use the following formula to calculate the ground distance:

Ground distance = Map distance / Map scale

Ground distance = 5 cm / 50 km = 0.1 cm per kilometer

So, the ground distance between the two places on the map is 50 kilometers.
