21) Flying to Seoul with a tailwind a plane averaged 208 mph. On the return trip the plane only averaged 162 mph while flying back into the same wind. Find the speed of the plane in still air
and the speed of the wind

false

step-by-step explanation:

the reason i say this is because for a certain length of sides you can pick any two and the length is wither equal or greater than the third side and in this case it's not.

3 + 5 = 8

8 is smaller than 9 which is the third side.

hope this : )

the solution, from the graphing of the two lines, is (3,2), i.e., x = 3, y = 2.
