Ann is driving down a street at 61 km/h.
Suddenly a child runs into the street.
If it takes Ann 0.724 s to react and apply
the brakes, how far will she have moved before
she begins to slow down?
Answer in units of m.
The units can be simplified into m/s, in which case you would have 61000/3600. Simplify that to 16 and 17/18. This is your meters per second, so multiply that by .724 to get the answer.
