Solution
Let the distance represented on the map be x cm.
The given information in the form of a table is as follows.
| Distance covered on road in (in km) | 18 | 72 |
| Distance represented on map (in cm) | 1 | x |
The distances covered on road and represented on map are directly proportional to each other. Therefore, we obtain
`18/1 = 72/x`
`=> x = 72/18 = 4`
Hence, the distance represented on the map is 4 cm
