We know that

using a graph tool
see the attached figure

<span>The diver reaches the surface when d = 0
</span>so
<span>0.5t (3.5t- 28.25)=0---------> the solution is
0.5t=0--------> t=0
and
</span><span>(3.5t- 28.25)=0----------> 3.5t=28.25--------> t=28.25/3.5--------> t=8.07 minutes
</span><span>

the time it takes for the diver to reach the surface is when the depth is zero
the time is 8 minutes

the answer is 
8 minutes</span>
