Let p represent the speed of the plane in still air

Let w represent the speed of the wind

600= (p+w)(4)

600= (p-w)(5)

600 divided by 4= 150= p+w

600 divided by 5= 120= p-w

150+120= 270=2p

--- ---

divide 2 2

=135 =p

p+w= 150

135+w= 150

-135 -135

--------------

w = 15

The speed of the plane in still air is 135 mph.

The speed of the wind is 15 mph.
