Question 1149885
.


<pre>
    On arrivals, the runway time is the time the plane touches down on the runway. The arrival gate time includes the time it takes 
    to taxi to the gate. On departures, the gate time is the time at which the plane pulls back from the gate.

OK. So, under these assumptions, the solution is as follows.



<pre>
Let u be the average speed of the aircraft at no wind, and let v be the average speed of the wind.


The flight "to there" is  4 hours 30 minute = 4.5 hours <U>in the air</U>.


The flight "back" is  5 hours 50 minute = {{{5}}}{{{5/6}}} = {{{35/6}}} hours <U>in the air</U>.


    u + v = {{{2383/4.5}}} = 529.555  mph.     (The effective speed with the wind)

    u - v = {{{2383/((35/6))}}} = 408.514 mph      (The effective speed against the wind)


From these equations,  u, or the plane speed at no wind, is  469.0 mph;   <U>ANSWER</U>

                       v, or the wind speed, is               60.5 mph.   <U>ANSWER</U>
