You can put this solution on YOUR website!
t, time for fast car to catchup to slower truck
d, distance that each traveled upon catchup
Uniform Travel Rates Rule, RT=D for rate time distance


___________________speed_______time______distance
TRUCK_______________60________t+1/6______d
CAR ________________66_________t_________d


Use the basic rule. Two equations as formulas for d, but each expression is equal.
