The scale of a map is 1:1,000,000. What are the real distances between two points if the distance between them on this map is: b

Dennis_Churaev [7]

Answer:

The real distance is $600,000\ cm$ or $6\ km$

Step-by-step explanation:

we know that

The scale of the map is $1:1,000,000$

that means

1 cm in the map-------> represent 1,000,000 cm in the actual (real distance)

by proportion

$\frac{1}{1,000,000}=\frac{0.6}{x}\\ \\x=0.6*1,000,000\\ \\x=600,000\ cm$

Remember that

$1\ km=100,000\ cm$

$600,000\ cm=6\ km$
