525 divided by 150 is 3.5
3.5= 3 hours and 30 mins
answer is b
Imposible triangle, lagest side must be > sum other sides.
We can see that the graph touches 
without crossing the x-axis (i.e. it is a double solution), and then there's another zero at 
(this time it's a crossing zero, so a single solution).
This leads, up to multiple, to the polynomial
If we impose the passing through 
we have
So, the polynomial is
Finally, to solve 
, simply look at the graph, searching for the points, where the graph is below the x-axis. You can see that this happens only if 
, so that's the solution to your question.
