Question

Find out the R.F of a map wchich is drawn to the scale of 5 cm to 1 km

Answer 1

Answer:

On the first map:

5 cm represents 1 km

So 1 cm represents 1/5 = 0.2 km

and 4 cm represents 4 x 0.2 = 0.8 km

On the second map:

3 cm represents 1 km

So 0.8 km will be represented by 3 x 0.8 = 2.4 cm.

The other way of looking at it is to say that the second map is 3/5 the size of the first map. 3/5 x 4 cm = 2.4 cm
