Question

The scale of a particle map is $1:100,000$. On the map, the school is shown to be $2.5cm$ away from Jatinder's house. How far is his house from the school? Express this answer in $km$.

Answer 1

Let the distance be $x$

$\Rightarrow 1:100000=2.5cm:x$

$\Rightarrow x=2.5\times 100000$

$\Rightarrow x=250000cm$

$\Rightarrow x=2.5km$

Hence,

$2.5km$ jatinder's house is away from the school.
