Asked by Kelly
Ann is driving down a street at 58 km/h. Suddenly a child runs into the street. If it takes Ann .71 s to react and apply the brakes, how far will she have moved before she begins to slow down? Answer in units of m.
When I converted 58km/h I got 16.111 m/s but now I'm not really sure how to solve problem.

You are on the right track. Your conversion to m/s looks good.
The question is how far does the car move in 0.71s.
distance = rate*time
= 16.111m/s * 0.71s
=11.44m
