Question

On a scale of map, 0.6 cm represents 6.6 km. If the distance between the points on the map is 80.5 cm, the actual distance between these points is

• A. 9 km
• B. 72.5 kg
• C. 190.75 km
• D. 885.5 km

Answer 1

The correct option is D 885.5 km

Let the required actual distance be $xkm$
More scale distance, More actual distance(direct proportion)
Hence we can write as scale distance $0.6:80.5::6.6:x$

$\Rightarrow 0.6x=80.5\times 6.6$

$\Rightarrow 0.1x=80.5\times 1.1$

$\Rightarrow x=80.5\times 11=885.5km$
