**Reiny**, Thursday, February 28, 2013 at 10:32pmspeed of plane in still air --- x mph

speed of wind ------------ y mph

so going with the wind, speed = x+y

against the wind, speed = x-y

x+y = 158

x-y = 112

add them

2x = 270

x = 135

then 135 + y = 158

y = 23

speed of wind is 23 mph, speed of plane in still air = 135 mph
