Physics question?

A race driver has made a pit stop to refuel. After refueling, he leaves the pit area with an acceleration whose magnitude is 4.40 m/s2; after 4.0 s he enters the main speedway. At the same instant, another car on the speedway and traveling at a constant speed of 60 m/s overtakes and pes the entering car. If the entering car maintains its acceleration, how much time is required for it to catch the other car?
