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
The correct answer would be D. When a hurricane reaches the land, its intensity decreases as a result of the friction and the lack of warm, moist air. The outer part of the hurricane would start to include that air from land which is drier and cooler which would increase the friction decreasing the strength of the hurricane.
