Question

Отрезу на карте длина которого 3,6 см , соответствует расстояние на местности в 72 км. Каково растояние между городами , есле на этой карте расстояние между ними 12,6 см

Answer 1

Масштаб карты 1÷2000000
7200000÷3.6=2000000
12.6×20000000=25200000см=252 км

Answer 2

72км=7200000см
7200000:3,6=2000000 (см)=20(км) расстояние на местности равное 1см на карте
12,6*2000000=25200000(см)=252(км) расстоние между городами

Answer 3

Calculation of Scale on the Map

To determine the distance between two points on a map, we need to understand the scale of the map. The scale represents the ratio between the distances on the map and the actual distances on the ground. In this case, we are given that a length of 3.6 cm on the map corresponds to a distance of 72 km on the ground.

To calculate the scale of the map, we can use the following formula: Scale = Distance on the ground / Length on the map

Using the given values, we can substitute them into the formula: Scale = 72 km / 3.6 cm

Now, we can calculate the scale: Scale = 20 km/cm

Calculation of Distance Between Cities

Given that the distance between the cities on the map is 12.6 cm, we can use the scale of the map to calculate the actual distance between the cities.

Using the scale of 20 km/cm, we can multiply it by the length on the map to find the actual distance: Distance = Scale * Length on the map Distance = 20 km/cm * 12.6 cm

Now, we can calculate the distance between the cities: Distance = 252 km

Therefore, the distance between the cities, if the distance on the map is 12.6 cm, is 252 km.

Please note that the information provided is based on the given scale and calculations.
