Answer:
25.2 km east
Explanation:
The relationship between velocity and displacement is given by:
[tex]v=\frac{d}{t}[/tex]
where
v is the velocity
d is the displacement
t is the time
In this problem, we have:
[tex]v=7 m/s[/tex] east is Rebecca's velocity
[tex]t=1 h=60 min=3600 s[/tex] is the time taken
Re-arranging the equation, we can find Rebecca's displacement:
[tex]d=vt=(7 m/s)(3600 s)=25,200 m=25.2 km[/tex]
and the direction is same as velocity (east)
