Question 1165533: A car is speeding past a stopped police officer at 100km/h, how long would it take the police officer to catch up to him at an acceleration of 3.6m/s? Answer by ikleyn(52781) (Show Source):
= .
The equation says: the distance covered by the police officer is equal to that covered by a violator.
Express all given data in uniform (consistent) system of units and solve the equation then
t = .

Comment from student: Thanks for answering my question, but I'm a little confused on the last equation.
Did you derive that equation from the first one or is that a separate equation?
My response : I derived the second equation from the first one.
For it, I canceled both sides in the first equation by the factor t.
