Choose the named scale of the map corresponding to the numerical 1: 250000

Choose the named scale of the map corresponding to the numerical 1: 250000: a) in 1 cm – 25 km. b) 1 cm – 250 km. c) 1 cm – 2.5 km. d) 1 cm – 2500 km.

Numerical scale is a simple fraction with one in the numerator. It shows how many real centimeters are contained in this unit on the map. Let’s translate our format: 250,000 cm, that’s 2.5 km. Therefore, our named format (B) is 1 cm 2.5 km.

There is also a simple rule of thumb to read large scales. It is necessary to remove 5 zeros from the denominator and we will get how many kilometers are in 1 centimeter.
