Find the scale of the map if the distance is 14 km corresponds to a segment of length on it: 0.7 cm; 2.5cm; 2.8cm.

For the convenience of the calculation, we will express the data according to the condition, the distance in centimeters on the map in kilometers. In a meter there are 100 centimeters, and in a kilometer there are 1000 meters, therefore, this distance on the map must be divided by 100 and by 1000:

0.7 cm = 0.7: 100: 1000 = 0.7: 100000 = 0.000007 km

2.5 cm = 2.5: 100000 = 0.000025 km

2.8 cm = 2.8: 100000 = 0.000028 km

Now we have the distance in kilometers on the terrain and on the map in the same units. To get the scale of the map, divide the distance on the ground by the distance on the map:

At 0.7 cm: 1: 2,000,000;

At 2.5 cm: 1: 560,000;

At 2.8 cm: 1: 500,000.

Answer: 1: 2000000, 1: 560000, 1: 500000.
