Question

Отрезок на местности длинной 3км изображен на карте отрезком 6км. какована карте длинна отрезка, изображающего отрезок 10км? какой отрезок на местности изображает отрезок на карте 1,8км?

Answer 1

1)Найдём масштаб 6км : 3км = 2 ( масштаб = 2:1); 2) 10км *2:1=20км; 3)1,8км :2*1=0,9км

Answer 2

Length of the Segment on the Map

To determine the length of the segment on the map that represents a 10 km segment in reality, we can set up a proportion using the given information. We know that a 3 km segment on the ground is represented by a 6 km segment on the map. Let's call the length of the segment on the map that represents a 10 km segment "x". We can set up the following proportion:

3 km / 6 km = 10 km / x

To solve for "x", we can cross-multiply and then divide:

3 km * x = 6 km * 10 km

3x = 60 km

x = 20 km

Therefore, the length of the segment on the map that represents a 10 km segment is 20 km.

Segment on the Ground Represented on the Map

To determine the length of the segment on the ground that is represented by a 1.8 km segment on the map, we can set up a proportion using the given information. We know that a 3 km segment on the ground is represented by a 6 km segment on the map. Let's call the length of the segment on the ground that is represented by a 1.8 km segment on the map "y". We can set up the following proportion:

3 km / 6 km = y km / 1.8 km

To solve for "y", we can cross-multiply and then divide:

3 km * 1.8 km = 6 km * y km

5.4 km = 6y

y = 0.9 km

Therefore, the segment on the ground that is represented by a 1.8 km segment on the map is 0.9 km.
