The distance on a map is 4.5 cm. The scale of the map is 1 : 1000. What is the actual distance?. Single choice.

Actual distance is 4500 cm (45 m).

Step-by-step explanation:

A scale is a representative fraction that can be used to either increase or decrease proportionally the dimension of a given object.

scale =

It is in the form of a ratio.

From the question, Distance on map = 4.5 cm,

scale = 1 : 1000

        =

scale =

Let the actual distance be represented by d.

So that,

=

⇒  d = 4.5 x 1000

       = 4500

    d = 4500

The actual distance is 4500 cm (45 m).

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.

the correct answer is d
