The answer would be 0.3316
For this case, the first thing we must do is define variables:
p: plane speed
w: wind speed
With the wind in favor, the speed is:
With the wind against the speed is:
Rewriting both equations, we have the following system of equations:
Then, solving the system of equations (graphically for example), we have the solution is:
Therefore, jet stream's speed:
Answer:
A) p + w = 960; p - w = 600; jet stream's speed = 180 km / h
Yes I can help you what is the problem sir
I think the answer is
x+3y+7
This is wrong.
It's supposed to be -4/15.
But try -4/5.
