One sails south at 15 mi/h and the other sails east at 20 mi/h. Find a function that models the distance D between the ships in terms of the time t (in hours) elapsed since their departure. : This is right triangle, legs formed by the path of the two ships distance between the ships is the hypotnenus a^2 + b^2 = c^2 ; a = 15t b = 20t c = d : d(t) = : d(t) = : d(t) = d(t) = 25t
