Answer:
maximum possible velocity = 
Explanation:
centripetal acceleration when the  car is going in the circle must be less than the maximum friction for the car to not slip.
centripetal acceleration 
where v is the velocity of car and r is the radius of circle 
maximum friction = umg
where u is the coefficient of static friction.
therefore
therefore maximum possible velocity =
