Question 984337
Use RT=D concept and if you want to make some of the numbers and relationships clear, use a data table.


<pre>
              speed       time      distance
GOING         350         (  )       d
BACK          250         (  )       d
Total                      3

</pre>


Fill in the missing time information.  This should enough to figure how to solve for both times each way and the distance either direction.


<pre>
              speed       time      distance
GOING         350         d/350       d
BACK          250         d/250       d
Total                      3

{{{d/350+d/250=3}}};
Solve for d; you can get each of the time values if you want, using found d.
