Question 1111713: Flying to Kampala with a tailwind a plane averaged 158 km/h. On the return trip the plane only averaged 112 km/h while flying back into the same wind. Find the speed of the wind and the speed of the plane in still air.

Plane speed= x km/h
wind speed= y km/h
with wind speed= (x+y)
against wind speed (x-y)
x+y =158
x-y = 112
solve
2x= 270
x=135km/h
plug x to get y
