Arlington bound car speed = x mph
Vernonville bound car = x+10 mph
distance = 144 miles
...
since they are travelling towards each other speed = 2x+10 mph
time = distance/speed
3/5 = 144/(2x+10)
3*(2x+10)=144*5
6x+30 = 720
6x=720-30
6x=690
x= 115 mph Arlington bound car speed
Vernonville bound car speed = 125 mph
