Given:-
With a tailwind, a aircraft can fly 672 miles in 3 hours. Against this same wind, the aircraft can fly the same distance in 4 hours.
To find:-
The effect of the wind and the average airspeed of the aircraft.
So now we average speed of aircraft is,
[tex]\begin{gathered} \frac{672}{3}=\frac{224\operatorname{km}}{hr},\frac{672}{4}=\frac{168\operatorname{km}}{hr} \\ \end{gathered}[/tex]So now the average speed of the aircraft is,
[tex]\frac{224+168}{2}=\frac{392}{2}=\frac{196\operatorname{km}}{hr}[/tex]So the average speed of the aircraft is 196km/hr
So now the wind speed difference is,
[tex]196-28=168,196+28=224[/tex]So the wind speed difference is 28km/hr
