Question : 14

Total: 40

On a map,

\frac{1}{3}\text{cm}

represents 5 km . If two towns

A

B

are 18 cm apart on the map, what is the actual distance between them?

$\;\;27\text{km}$
$\;\;30\text{km}$
$\;\;240\text{km}$
$\;\;270\text{km}$

Solution:

Concept:

Use the map scale to convert map distance into actual ground distance.

Explanation:

Given:

\frac{1}{3}\text{ cm}

on the map

= 5\text{ km}

on the ground.

So,

1\text{ cm}

on the map

= 5 \times 3 = 15\text{ km}

.

Now, the distance between towns

A

and

B

on the map is

18\text{ cm}

.

Actual distance

= 18 \times 15\text{ km}

.

Actual distance

= 270\text{ km}

.

Answer:

D.

\;\;270\text{ km}
