Setting d = 0 gives the points where she is at the surface.
therefore 0= 0.1t^2 - 3.5t + 6
apply the quadratic formula to get t = (3.5+- √12.25-4*0.1*6)/0.2
t = (3.5 <span>3.1384709653)/0.2
t= </span>1.80764517352 and <span>33.1923548265
</span>subtract the 2 to get the time difference between entry and exit you get
Δt = <span>31.384709653 seconds
</span>
That's as long as I haven't made a mistake :D
