Assuming that all cars have equal speeds, which car has the acceleration of the greatest magnitude, and which one has the acceleration of the least magnitude?

I think for this problem, there should have been choices in which we could choose our answers from. However, on a general note the acceleration is calculated through the equation,

a = v/t

where v is the velocity and t is the time. Since, acceleration is inversely proportional to time, the car which will take longer time to reach a certain velocity will have the least acceleration and the car which will take the shortest time will have the least acceleration.
