Both travel for assumed same time, t.  Slow truck travels less distance than the fast truck.


____________________rate______time______distance
SLOW________________60_________t________d-50
FAST________________70_________t_________d


Both times are equal.
{{{highlight_green((d-50)/60=d/70)}}} based on T=D/R.


{{{70(d-50)=d*60}}}
{{{7(d-50)=6d}}}
{{{7d-350=6d}}}
{{{d=350}}}


Find t.
{{{t=d/R}}}
{{{t=350/70}}}
