We have equation of motion
S = ut + (1)/(2) at^2, here S = displacement, u = initial velocity, t is the time taken and a is the acceleration.

In this case displacement = 160 m

Initial velocity = 30 m/s

Acceleration =
0 m/s^2

Substituting we will get
160 = 30 *t + (1)/(2)*0* t^2\\ \\ 160 =30t\\ \\ t = 160/30\\ \\ t = 5.33 seconds

So car will take 5.33 seconds to travel 160 m.
