Given that she slides at a rate of 8m/s and that she was 5 m of the ground after 3 seconds, the number of seconds it takes her to reach the ground from the current position is given by:
[tex]t=\frac{d}{s}=\frac{5}{8}seconds[/tex]
Therefore, the number of seconds it takes her to slide to the ground from the top is given by:
[tex]3+ \frac{5}{8} =3 \frac{5}{8} [/tex]
