Flying to kampala with a tailwind a plane averaged 158 km/h. on the return trip the plane only averaged 112km/h while flying back into the same wind. find the speed of the wind and the speed of the plane in still air.

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 instill air. Let plane speed be "p". Let wind speed be "w". Equations: p + w = 158 p - w = ...
