Question

I do not get this question at all,this is composite functions and all my answers to a) to c) is wrong,can someone please help me with this problem :)?

Suppose a ship is sailing at a rate of 35km/h parellel to a straight shoreline. The ship is 10km from shore when it passes a lighthouse at 11am.



a)
Let k be the distance between the lighthouse and the ship. Let d be the distance from the ship has travelled since 11am. Express k as a function of d. Please include a diagram.


b)
Express d as a function of t, the time elapsed since 11am.


c)
Find k∘d . What does this function represent?

Yes, it is composite, so use d = v t which was part B

and please use one name so I do not have to search all over for your earlier attempt.
