Question

2. A streamer goes downstream and covers the distance between two ports in
three hours while it covers the same distance upstream in 4 hours. If the speed of
the stream is 3km/hr, find the speed of the streamer in still water.​

Answer 1

Answer:

Let the speed of the steamer be s

and the distance between two points be d

Then d/(x+3)=3 d=3.(x+3)

and d/(x-3)=4 d=4.(x-3)

4(x-3)=3(x+3)

4x-3x=9+12

x=21Ans
