What is the scale if 3 cm on the map correspond to 120 km in the actual distance

The scale is 1 cm : 40km

The map is a scale drawing

A scale drawing is a reduced image of another image.

Scale of the map = dimensions of the scale drawing / dimensions of actual image

3cm /120 km

To simplify, divide both sides of the equation by 3

1 cm : 40km

1 cm : 40 km.

Step-by-step explanation:

We are asked to find the scale factor of a map, when 3 cm on the map correspond to 120 km in the actual distance.

To find scale of the map, we will divide actual distance by distance on map as:

Since 1 cm on map corresponds to 40 km in the actual distance, therefore, the scale is 1 cm : 40 km.

step-by-step explanation:

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
