Question 1102920
x, distance from airport to corporate office 
<pre>
             SPEED       TIME         DISTANCE

DROVE          50       (450-x)/50     450-x

FLEW          100         x/100          x

Total                      5            450
</pre>

Variables could be assigned differently; or two variables could be used, either both for time or both for distances; but the arrangement shown in the table might be most efficient.


{{{highlight_green((450-x)/50+x/100=5)}}}
Solve this equation for x.
