For this question

U should know basic three kinematics equations

Necessary here though

a.

b.

c.

Using equations 1 and 3

v-final velocity

u-initial velocity

a-uniform acceleration

t-time taken for the motion

S- is the displacement

Now here,car is having inital speed i.e. u=

and as the car stops v=0

and time taken (t ) is 1.88 seconds

Substitute the above value in the above equation and u will get the acceleration-a

Now the third kinematic equation which give the relation between the final velocity initial velocity and acceleration and the distance travelled

here substitute the v then u and a to get the displacement covered by the car during skidding by equation 3
