A red car and a green car, identical except for the color, movetoward each other in adjacent lanes and parallel to an xaxis. At time t = 0, the red car is atxr = 0 and the green car is atxg = 220 m. If the red car has a constantvelocity of +20 km/h, the cars pass each other at x =44.6 m, and if it has a constantvelocity of +40 km/h, they pass each other at x =76.6 m.

(a) What is the initial velocity of the green car?

(b) What is the acceleration of the green car?

I know its similar to the one that cramster has posted but somenumbers are off and i am really confused on it
