10. A plane travelling in one direction has a tailwind and takes 3 h to travel 960 km. When it makes the return trip, it has a headwind and takes 4 h to travel the same distance. Assuming the tailwind speed was the same as the headwind speed, what was the speed of the wind? What was the speed of the plane? (Hint: Think of the faster speed as the plane speed plus the tailwind speed.]

Ответ:
