Two cars, A and B, travel in a straight line. The distance of car A from the starting point is given as a function of time by xA(t) = αt + βt^2, with α = 2.60 m/s and β = 1.20 m/s^2. The distance of car B from the starting point is xB(t) = γt^2 - δt^3, with γ = 2.80 m/s^2 and δ = 0.20 m/s^3.
Which car is ahead just after they leave the starting point?
At what time(s) are the cars at the same point?

I wasn't able to parse your question, but the HE.NET team is hard at work making me smarter.
