SOLVE IT....

Answer 1

HEY here s it answer

Let 'x' be the speed of the streamer in still water.
Distance in both cases is same (Suppose it as d).  We know, speed=distance/time.      So when downstream,
x + 2 = d/4
=> d = 4x + 8.  When upstream,
x - 2 = d/5
=> d = 5x - 10.  Since, d is same
=>4x + 8 = 5x - 10
=> 5x - 4x = 10+8
=> x = 18.
Hence, speed of the streamer in still water is 18 kmph.

I HOPE IT HELPED. PLSS MARK BRAINLIEST
