A weather plane took to the skies to measure the speed of the jet stream. The plane flew 1920 km with the jet stream as a tail w
Alex
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:
 p + w = 1920/2

 With the wind against the speed is:
 p - w = 1920 / 3.2

 Rewriting both equations, we have the following system of equations:
 p + w = 960

p - w = 600
 Then, solving the system of equations (graphically for example), we have the solution is: 
 p = 780

w = 180
 Therefore, jet stream's speed:
 w = 180 km / h

 Answer:
 
A) p + w = 960; p - w = 600; jet stream's speed = 180 km / h

antoniya [11.8K]

Answer:

X=30; Z=80; Y=70

Step-by-step explanation:

The straight lines equal 180 and you subtract 180 to 150 and 180 to 100 to get 30 and 80 and the inside of a triangle is 180 and you subtract 30 and 80 to 180 to get 70.
