b)8days
Step-by-step explanation:
15x16
=240
240÷20
=12days
24x15
=360
360÷45
=8 days

Fun!
The center of the hyperbola is the midpoint of its foci. The distance between the foci is 43-9=34. So they're 17 from the center.
We have coordinates
F1(0,17)
F2(0,-17)
Let's call the vertex of the hyperbola V. We have
V(0,13)
This is a vertical hyperbola so the equation is of the form

The vertices for a vertical hyperbola like this are (0, a) and (0,-a)
So we have a=13
The distance c from the foci to the center is given by


That says our hyperbola's equation is

That's our answer.
