Question

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

Answer 1

Actual Distance =120 Km

We have to map 120 Km in the scale of  3 Cm.

i.e, 3 Cm = 120 Km

→  1 cm = (120÷3) Km

→ 1 cm = 40 Km

So, if you scale 3 cm on the map correspond to 120 km,then

you have to scale , 1 Cm= 40 Km

Drawn the graph for you below.

Answer 2

Answer:

1 cm = 40 km.

Step-by-step explanation:

Actual distance = 120 kilometers

The distance on the map = 3 centimeters

Scale map = $\frac{\text{Actual distance}}{\text{distance on map}}$

                  = $\frac{120}{3}$

                  = 40

1 centimeters = 40 kilometers

The scale of the map is 1 cm = 40 km.
