Question 319106
First off, this is not an algebra problem.
Secondly, there are many factors that contribute to braking distance.
Speed is only one of them.
There is not enough information to solve.
If there was a brick wall  in the way, then the answer might be 1-2 milliseconds.
If the car was on an icy road, then it could be several thousand feet. 
You see what I mean.
