Question 1149196
<br>
x = wind speed<br>
180+x = airplane speed with wind
180-x = airplane speed against the wind<br>
424/(180+x) = hours with the wind
424/(180-x) = hours against the wind<br>
The total time was 8 hours:<br>
{{{424/(180+x)+424/(180-x) = 8}}}<br>
The solution is not a "nice" number; so the equation is most easily solved by using a graphing calculator to graph the two expressions on either side of the equal sign and finding their point of intersection.<br>
