Question

- A map shows the various tourist locations in a city. The scale of the map is 2 cm = 500 m. Determine:
(a) the actual distance between two places if the distance between them on the map is 7 cm.
(b) the distance between two places on the map if the actual distance between them is 1800 m.
​

Answer 1

Answer:

(a)

$2cm = 500m \\ 1cm = 250m \\ 7cm = 250 \times 7 = 1750cm$

(b)

$250m = 1cm \\ 1800m = x \times 250 \\ x = \frac{1800}{250} = 7.2cm$
