A plane can fly 600 km per hour with the wind and 450 kilometer per hour against the wind. Find the speed of the wind and the speed of the plane in still air.

Let plane speed in still air be "p".
Let wind speed be "w".
----------------
p + w = 600
p - w = 450
----
2p = 1050
p = 525 mph (plane speed in still air)
----
Solve for "w":
p + w = 600
525 + w = 600
w = 75 mph (wind speed)
