D=RT
135=45T FIRST CAR.
135=55(T-.5) SECOND CAR.
45T=55(T-.5
45T=55T-27.5
45T-55T=-27.5
10T=-27.5
T=27.5/10
T=2.75 HOURS FOR THE TRIP TIME
45*2.75=123.75 MILES IS THE POINT WHERE THEY MEET.
55(2.75-.5)=55*2.25=123.75 DITTO.
2.75-.5=2.25 HOURS THE SECOND CAR WILL CATH UP WITH THE FIRST CAR.
yes THEY WILL MEET BEFORE THEY ARRIVE @ THE FOOTBALL GAME.
123.75 MILES IS LESS THAN 135 MILES.
