Пошаговое объяснение: 1) 1 : 2000000

2) расстояние между двумя городами - 3 см

3) 2000000 х 3 = 6000000 ( см)

4) 6000000 см = 60 км

1) 1: 2000000

2) расстояние между двумя городами - 15 мм (1,5 см)

3) 2000000 х 1,5 =3000000 (см)

4) 3000000 см= 30 км

3,15/х = 1/2000000
х = 3.15 * 2000000 / 1
х = 6300000 / 1
х = 6300000

6300000 см = 63 км
Расстояние на местности 63 км
