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?
Let the distance measured on map be xcm
The above information in the form of table is as follows:
Distance covered on Map in cm | 1 | x |
Distance covered on road in km | 18 | 72 |
The above information is in direct proportion.
Therefore,
1 × 18 = x × 72
→x = 4 cm
