Question

Отрезку на карте длиной 2 см соответствует расстояние на местности в 8 км .какой маштаб карты?Какому расстоянию на местности соответствует отрезок на карте длинной в 4,5 см?

Answer 1

8км=8000м=800000см
Масштаб 2см/800000см=1/400000
А отрезку 4.5 см соответствует  4.5*400000=1800000см=18000м=18км

Answer 2

Map Scale Calculation

To determine the scale of the map, we can use the given information that a 2 cm distance on the map corresponds to an 8 km distance on the ground.

Let's calculate the scale of the map using this information:

1. Convert the given distance on the map to kilometers: 2 cm * (8 km / 2 cm) = 8 km.

Therefore, the scale of the map is 1:8, meaning that 1 cm on the map represents 8 km on the ground.

Calculating Distance on the Ground

Now, let's calculate the distance on the ground that corresponds to a 4.5 cm segment on the map.

1. Use the scale of the map to convert the distance on the map to kilometers: 4.5 cm * (8 km / 1 cm) = 36 km.

Therefore, a 4.5 cm segment on the map corresponds to a distance of 36 km on the ground.
