r = speed of truck
t = time for the truck
__________________speed___________time__________distance____Equations
CAR_______________r+20____________t-2___________350_________
TRUCK______________r______________t_____________350___________
The system of equations will produce a quadratic equation, and you will need the truck's equation for substitution two ways.
