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 km
(c)190.75 km
(d)885.5 km
Answer
Answer (as printed): D
Explanation
Let the actual distance be $x \mathrm{km}$. Then, More distance on the map, More is the actual distance (Direct Proportion). $\therefore 0.6:80.5::6.6:x \Leftrightarrow 0.6x = 80.5 \times 6.6 \Leftrightarrow x = \frac{80.5 \times 6.6}{0.6} \Leftrightarrow x = 885.5$.
