Answer:

  • wind: 23 km/h
  • plane: 135 km/h

Step-by-step explanation:

The difference in plane speeds is twice the wind speed, as the wind is adding in one case and subtracting in the other. So, the wind speed is ...

  (158 -112)/2 = 46/2 = 23 . . . . km/h

The plane speed is 23 km/h more than the slower speed, so is ...

  112 +23 = 135 . . . . km/h

The wind speed is 23 km/h; the plane speed is 135 km/h.
