Check the picture below.
now, keep in mind that ship B is going at 20kph, thus from noon to 4pm, is 4 hours, so it has travelled by then 20 * 4 or 80 kilometers, thus b = 80.
whilst the ship B is moving north, the distance "a" is not really changing, and thus is a constant, that matters because the derivative of a constant is 0.

Answer:
The correct option is b.
Step-by-step explanation:
The given function is
We need to find the value of f(-2). It means we have to find the value of given function at x=-2.
Substitute x=-2 in the given function to find the value of f(-2).
On simplification we get
The value of f(-2) is 11. Therefore the correct option is b.
