Question 1052741
A very typical catchup-travel type problem.  Basic constant travel rate rule is RT=D.  Time is best handled in quantities, and not as points on a time-line, but this is only to make handling easier values for analyzing and solving the problem.


Only a data table is presented here.   You do the rest.

<pre>
                  SPEEDS           TIME           DISTANCE
FIRST             r                t+2             d
SECOND            r+30              t              d
</pre>


Excuse me.  I left something out.
{{{highlight_green(t+2=5)}}}.


Here is an adjustment to the data table, using according to the meaning of the time points in the description:
<pre>
                  SPEEDS           TIME           DISTANCE
FIRST             r                 5              d
SECOND            r+30              3              d
</pre>

NOW you can do the rest.
