Answer:
18
Step-by-step explanation:
Let the steamer speed will be x.
Downstream speed = (x+2)
Distance between the points = 4(x+2) ---------- (1)
Upstream speed = (x-2)
Distance between the points = 5(x-2) ------------ (2)
On solving (1) and (2), we get
4(x+2) = 5(x - 2)
4x + 8 = 5x - 10
x = 18
speed of the steamer in still water = 18 km/hr
