One segment on the map is 4.5cm long and the other 6.5cm. Find the length of the first segment on the terrain if the second segment on the terrain has a length of 7.8 km.
The length of the first segment on the ground relates to its length on the map (4.5 cm), as the length of the second segment on the ground (7.8 km) refers to its length on the map (6.5 cm). We make the proportion:
X km / 4.5 cm = 7.8 km / 6.5 cm, where X is the length of the first segment on the ground, km
We solve the proportion:
X = (4.5 * 7.8) / 6.5
X = 5.4 km.
Answer: The length of the first section on the terrain is 5.4 km.
