Answer:

83.055  m

Explanation:

According to the given scenario, the calculation of skid distance is shown below:-

S = \frac{1}{2} \times (u + v) \times t

Where  

u = 11.3

v = 0

t = 14.7

Now placing these values to the above formula,

So,

S = \frac{1}{2} \times (11.3 + 0) \times 14.7

= 83.055  m

Therefore for computing the skid distance we simply applied the above formula i.e by considering the all items given in the question
