Question 508305
It's similar to this one:
------------------
Flying with the wind, an airplane can travel 1500 km. in 2.5 hours, but flying against the wind, the airplane requires 0.5 hour more to make the return trip. find the speed of the airplane in still air and the speed of the wind.
------------
1500/2.5 = 600 km/hr
1500/3 = 500 km/hr
-----------------
The plane's airspeed is the avg, = 550 km/hr
The wind speed is the difference = 50 km/hr
