Answer:
Step-by-step explanation:
Let the distance between the two ports be x km.
Then, speed downstream = x/4
And speed upstream = x/5
Speed of the stream,
= [speed downstream - speed upstream] / 2
= (x/4 - x/5)/2
Or, (5x -4x)/40 = 2
Or, x/40 = 2
Thus, x = 80 km.
Distance between two ports = 80 km.
