The actual distance will be 12 km.
<u>Explanation</u>:
The scale of the map is 1:250000
1 cm in the map represents 250000 cm.
250000cm=2500 m=2.5 km
the measurement in the map is 4.8 cm
since 1 cm represents 250000 cm or 2.5 km
The actual distance represented by 4.8 cm on the map = 4.8*250000 cm =1,200,000 cm=12000 m=12 km
Answer: b
Explanation: temperate climates with adequate rainfall
The Congo and Niger rivers have interesting irregular courses, and instead of going just in a certain direction, they circle around big areas. This is due to the shape of the landscape, and also because of the types of rocks in the surrounding areas where these two rivers flow.
The shape of the landscape is crucial in the course of a river, since every river is moving through the lowest parts where there isn't obstacles, so these rivers have followed that pattern and it turned out to give them irregular course. Also, the types of rocks on their way are very important, so these rivers managed to get through the sediment rocks as they are easy to erode, but haven't been able to break through the igneous rocks that are much harder.
