In 2 1/2 hours an airplane travels 600 km against the wind. It takes 50 min to travel 300 km with the wind. Find the speed of the wind and the speed of the airplane in still air

Solution

speed against the wind= 600/2.5= 240 km/h

And speed of the plane with the wind= 300/50/60= 360 km/h

speed of plane is 1/2(360+240)= 300 km/h

speed of wind is 1/2(360-240)=60km/h
