Answer:

Rowing speed = 8km/hr

Current speed = 4km/hr

Pls mark as brilliantist

Here the explanation

Step-by-step explanation:

Rowing speed in still water is 8km/h

Speed of the water current is 4km/h

Given data :

Downstream speed = 24km/2h = 12km/h

Upstream speed = 8km/2h= 4km/h

Let,the rowing speed = x km/h

And current speed = y km/h

So,

x+y=12...(1)

And, x-y = 4 ...(2)

If we subtract (2) from (1)

We will get

(x + y) - (x - y) = 12 - 4

x + y - x + y = 8

2y = 8

y = 4

Now, putting the value of 'y' into (1) we get,

x + 4 = 12

x = 12 - 4

x = 8

So, the rowing speed is 8km/h. (Answer)

And the current speed is 4km/h. (Answer)

Answer:

8. & 4

Step-by-step explanation:

LET, SPEED IN STILL WATER = X

AND, =SPEED OF CURRENT =Y

AS PER QUESTIONS

X+Y=24/2=12

and X-Y=8/2=4

SO, X+Y+X-Y=12+4

OR, 2X=16

SOX=8AND Y=4

X+Y=
