Answer:
160
Explanation:
To solve this we will use the equation
Distance= Velocity * Time
We will first need to calculate the time flown
So we have
960=480*time
Divide and get time=2
We now need to find the new velocity considering wind speed and we can do this by writing a new equation
We have
640=velocity*2
divide and get that velocity=320
This is the speed that the plane was going with the wind resistane which means that to calculate the wind resistance you subtract 320 from the plane's normal speed of 480
so 480-320=160
