On a map, a distance of 5 cm represents an actual distance of 15 km. Write the ratio of the scale of the map.

Solution

First we need to convert $15$ km in cm to form the ratio.
$1 k m = 100000 c m$
$∴ 15 k m = 15 \times 100000 = 1500000 c m$
The ratio will became $5 : 1500000$
$= \frac{5}{1500000}$
$= \frac{1}{300000}$ by reducing.
Ratio is $1 : 300000$
