Question

On a scale map $0.7cm$ represents $8.4km$. If the distance between two points on the map is $46.5cm$, what is the actual distance between the points?

• A. $56km$
• B. $55.80km$
• C. $62.80km$
• D. $72km$

Answer 1

Answer: (B)

$55.80km$

Given $0.7$cm represents $8.4$ km

$46.5$ cm represents $x$

By proportionality

$\frac{0.7}{46.5}=\frac{8.4}{x}$

$x=\frac{8.4\times 46.5}{0.7}$

$x=55.80km$
