Question 544767: flying to kampala with a tailwind a plane averaged 158km/h. on return trip the plane only averaged 112km/h while flying back into the same wind. find the speed of thw wind and the speed of the plane in still air. Answer by mananth(16946) (Show Source):
You can put this solution on YOUR website! speed of wind in still air = x kmph
speed against wind = y kmph
with wind speed = 158 kmph
x+y=158
x-y=112
Add the two equations
2x=270
/2
x= 135 kmph speed of plane.
plug x in x+y=158
135+y=158
y=23 kmph
