6.) Rashmi has a road map with a scale of 1 cm representing 18 km. She drives on a road for 72km. what
would be her distance covered in the map?​

Answer 1

Let the distance measured on map be x cm

The above information in the form of table is as follows:

The above information is in direct proportion because distance covered in cm will increase or decrease with distance covered in km.

Therefore,

1 × 18 = x × 72

x = 4 cm

Method 2:1 cm on map = 18 km on road1 km on road = 1/18 cm on map72 km on road = 1/18 × 72 cm on map = 4 cm on map.
