On a certain map of India the actual distance of 1450 km between two cities Delhi and Kolkata is shown as 5 cm. What scale is used to draw the map ?

A. $$1:15 \times {10^6}$$

B. $$1:20 \times {10^6}$$

C. $$1:25 \times {10^6}$$

D. $$1:29 \times {10^6}$$

Answer: Option D

Solution(By Examveda Team)

5 cm on the map represents 1450 km
∴ 1 cm on the map represents $$\left( {\frac{{1450}}{5}} \right)$$  km = 290 km
Hence, the scale is 1 cm : 290 km i.e., $$1:29 \times {10^6}{\text{ }}$$
$$\left[ {\because 290{\text{km}} = \left( {29 \times {{10}^6}} \right){\text{cm}}} \right]$$
