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=
