A ship is moving at a speed of 30 kmyh parallel to a straight shoreline. The ship is 6 km from shore and it passes a lighthouse at noon.(a) Express the distance s between the lighthouse and the ship as a function of d, the distance the ship has traveled since noon; that is, find f so that s − f(d).(b) Express d as a function of t, the time elapsed since noon; that is, find t so that d − t(t).(c) Find f o g. What does this function represent?
