Answer:
13.3 m
Explanation:
During the reaction time of Ann, her velocity is constant, so the distance travelled during that time is given by
[tex]d=vt[/tex]
where
v is the velocity
t is the reaction time
First of all, let's convert the velocity from km/h to m/s:
[tex]v=64 km/h \cdot \frac{1000 m/km}{3600 s/h}=17.8 m/s[/tex]
The reaction time is
t = 0.747 s
So, the distance covered during this interval is
[tex]d=(17.8)(0.747)=13.3 m[/tex]
