Rashmi has a road map with a scale of 1 cm representing 18 km. She drives on a road for 72 km. What would be her distance covered in the map?
Share
Let distance covered in the map be x.
Actual distance (in km) 18 72
Distance covered in map (in cm) 1 x
Here actual distance and distance covered in the map are in direct proportion.
∴ 18/1 = 72/x ⇒ xX18=72×1 ⇒x=72×1/18 = 4cm
Hence, the distance covered in the map is 4 cm.
