Question 278624: A plane is moving at 180km/h west when it hits a tailwind of 22km/h. What is the final velocity. Draw the vector.
I'm totally lost sorry. I assume the speed could be 202 km/h but that still doesn't help me figure out velocity without having any other parameters such as gravity or time
Thank you for your help.

You can put this solution on YOUR website! A tail wind is a wind from the tail, and it's added, so 202 km/hr is correct (that's the groundspeed).
-----------------
I don't know why it's called "final velocity", tho, resultant is more appropriate.
---------------
For vectors, use 0/360 degs as north, then west is 270º.
The plane's vector is 180 units long in the 270º direction. The wind is 22 units long in the same direction. The vectors are end to end, making the length 202 in the same direction.
