Question

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

Answer 1

1 cm = 40 km.

Explanation:

Actual distance = 120 kilometers

The distance on the map = 3 centimeters

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

=
`(120)/(3)`

= 40

1 centimeters = 40 kilometers

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

Answer 2

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
