Question 1096006
.
<pre>
Let D be one way distance, in miles.


{{{D/180}}}  is the time for the flight "to there",

and  {{{D/120}}}  is the time for the flight back.


In  all

{{{D/180}}} + {{{D/120}}} = 5 hours.


Multiply both sides by 360 to get

2D + 3D = 5*360  ====> 52D = 5*360  ====>  D = 360 miles.
</pre>

Solved.


One way distance is 360 miles.


The round trip is 720 miles.
