Answer:
Speed of boat in still water is 6km/h
Speed of current is 4km/h
Step-by-step explanation:
We know speed = distance / time
Let the speed of boat in still water be x
Let the speed of current be y
Hence the speed of boat, down stream =
Distance downstream = 20km
Time taken = 2 hours
We have
......(1)
Speed of boat upstream =
Distance upstream = 4
Time taken = 2
We have
...(2)
Adding (1) & (2)
Substituting in (1) we get
The answer is 14.4

How to estimate the actual area of the forest in square kilometers?</h3>
Given: Scale of the map exists at 1:250000.
(a) Distance between two cities = 80 km
= 80000 m
= 8000000 cm
Distance on map = 8000000 1/ 250000
= 32 cm
(b) Area of map = 6 cm²
Actual area = cm²
cm²
= 37.5 km²
Therefore, the distance on map exists 32 cm and actual area exists 37.5 km².
