Question

Rakesh has a road map with a scale of 1 cm representing 7 km. He drives on a road for 80 km. What would be his distance covered in the map?

• A. 11 cm
• B. 11.53 cm
• C. 11.42 cm
• D. 11.75 cm

Answer 1

The correct option is C 11.42 cm

$\text{Let,}x\text{represent distance on map and y represent the distance on road.}{x}_1=1\text{and}{y}_1=7x_2=?\text{and}{y}_2=80\frac{x_1}{y_1}=\frac{x_2}{y_2}\Rightarrow \frac{1}{7}=\frac{x_2}{80}\Rightarrow x_2=\frac{80}{7}=11.42cm$
