Question

hi guys
pls help me plss​

Answer 1

Answer:

18 km/hrs

Explanation:

Let the speed of the stream in still water be x km/h

Then, the speed of downstream = (x+2) km/h

and the speed upstream = (x-2) km/h

Given, distance covered in 4 hrs downstream

= distance covered in 5 hrs upstream

.•. 4(x+2) = 5(x-2)

= 4x+8 = 5x -10

= 4x-5x = -10-8

= x = 18 km/h
