Explanation:
The relationship between velocity and displacement is given by:
where
v is the velocity
d is the displacement
t is the time
In this problem, we have:
east is Rebecca's velocity
is the time taken
Re-arranging the equation, we can find Rebecca's displacement:
and the direction is same as velocity (east)
