Question 1065407
<pre>
                SPEED      TIME       DISTANCE
BEN              2         t+1.5        d
AMANDA           4          t           d
</pre>


RT=D, constant travel rates rule for rate R, time T, distance D.


{{{system(2(t+1.5)=d,4t=d)}}}


Distance for each is the same d.


{{{2(t+1.5)=4t}}}

{{{t+1.5=2t}}}

{{{t=1.5}}}------------- One and a half hours for Amanda to catch-up to Ben.
