<h2>
Speed of plane = 1110 kmph</h2><h2>
Speed of wind = 150 kmph</h2>
Step-by-step explanation:
Let the speed of plane be p and speed of wind be w.
Flying against the wind, an airplane travels 5760 kilometers in 6 hours.
Here
             Speed = (p-w) kmph
             Time = 6 hours
             Distance = 5760 kmph
             Distance = Speed x Time
             5760 = (p-w) x 6
                p-w = 960 -----eqn 1  
Flying with the wind, the same plane travels 6300 kilometers in 5 hours.
Here
             Speed = (p+w) kmph
             Time = 5 hours
             Distance = 6300 kmph
             Distance = Speed x Time
             6300 = (p+w) x 5
                p+w = 1260 -----eqn 2     
eqn 1 + eqn 2
                 p-w + p +w =  960 + 1260
                   2p = 2220
                     p = 1110 kmph
Substituting in eqn 2
                 1110 + w = 1260
                          w = 150 kmph
Speed of plane = 1110 kmph
Speed of wind = 150 kmph
 
        
        
        
Hello from MrBillDoesMath!
