Question

The distance between the school and the Ravi's house is 20 km. What will be the distance on a map scaled at 1 cm = 2 km?

• A. 20 cm
• B. 12 cm
• C. 8 cm
• D. 10 cm

Answer 1

The correct option is D 10 cm

Scale: 1 cm = 2 km
$\therefore 1\text{km}=\frac{1}{2}\text{cm}$

Actual distance between the school and Ravi's house = 20 km

Therefore, Distance on the map
$=20\times \frac{1}{2}=20÷2=10\text{cm}$
