Hard question thx for the points give me brainlest points
The easiest way would be to subtract 112 from 158 to get 46 that is the difference. Then divide by 2 to find the speed of wind, in this case that would be 23. So the wind speed was 23 km/h and to get the plane speed add or subtract 23 from the sped of the plane (112+23 or 158-23) to get 135 km/h so the plane moved at 135 km/h while the wind speed was 23 km/h
