Question

101. A steamer goes downstream and covers the distance between two
ports in 3 hours. It covers the same distance in 5 hours when it goes
upstream. If the stream flows at 3 km/hr, then find what is the speed
of the steamer upstream?​

Answer 1

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

Answer 2

Answer:

9 km/ h
