Velocity : `ms^(-1)` :: acceleration : ?

Particle A is moving along X-axis. At time t = 0, it has velocity of 10 ms^(-1) and acceleration -4ms^(-2) . Particle B has velocity of 20 ms^(-1) and acceleration -2 ms^(-2) . Initially both the particles are at origion. At time t = 2 distance between the particles are at origin. At time t = 2 s distance between the particles is
