Question

7. On a certain map, 5 cm represents a kilometer. What is the distance apart of two points which are 8.4 cm apart on the map?

Answer 1

$\sf5 \: cm\: \: \: \: \: \: \: \: \: \: \longrightarrow \: \: \: \: \: \: \: \: \: \: 1 \: km \\ \\ \sf 1 \: cm\: \: \: \: \: \: \: \: \: \: \longrightarrow \: \: \: \: \: \: \: \: \: \: \frac{1}{5} \: km$

Therefore,

$\huge \bf Required \: \: Distance \\ \\ \tt= > \frac{1}{5} \times8.4 \\ \\ \tt = > \frac{8.4}{5} = \frac{84}{50} \\ \\ \tt= > \frac{42}{25} = \red{1.68 \: km}$
