Question 1083311
<pre>
                   SPEED        TIME          DISTANCE

A to B             r           {{{192/r}}}               192

B to C             r+16        {{{240/(r+16)}}}               240

Difference                  {{{6/60=1/10}}}
</pre>

The B to C part of the trip took MORE time than the A to B part of the trip.

{{{highlight_green(240/(r+16)-192/r=1/10)}}}
Solve this equation for speed r, the speed for the first part of the trip.
