We have 3 cases here to calculate:
Case 1: Delhi to Jaipur
The distance on the ground is 250 km; we need to find how much that equals to on the map. Since 1 cm is equal to 200 km on the ground, we can find the equivalent distance on the map by dividing the ground distance by the scale.
Thus, the distance from Delhi to Jaipur on the map is 250 km / 200 = 1.25 cm.
Case 2: Raigarh to Champa
This case is reversed; the distance on the map is 12 cm and we need to translate this distance to the actual ground. Remember that 1 cm on the map is equivalent to 200 km on the ground, so we do a simple multiplication here:
The distance from Raigarh to Champa on the ground is 12 cm * 200 = 2400 km
Case 3: Goa to Chennai
Similar to the first case, the ground distance is 900 km and we need to calculate the map distance. Again, we do this by dividing the ground distance by the scale:
Thus, the distance from Goa to Chennai on the map is 900 km / 200 = 4.5 cm.
In conclusion, the distances on the map are: Delhi to Jaipur - 1.25 cm, Raigarh to Champa - 2400 km (on the ground), and Goa to Chennai - 4.5 cm.
