At noon, ship a is 40 nautical miles due west of ship b. ship a is sailing west at 18 knots and ship b is sailing north at 17 kn
igor_vitrenko [27]

The distance between the ships changing at 92.29 Knots

  • Using the position of ship A as the reference point, at time t measured in hours past noon, ship A is 18 t miles west of this point and ship B is 40 + 17t north of this point.
  • The distance between ships is then

                              d(t) = \sqrt{(18t)^{2} + (40+17t)^{2} } \\

The rate of change of distance is -

                              \frac{dd}{dt} = \frac{36t + 2(40 + 17t)17}{2\sqrt{18t^{2} + (40 + 17t) } }

after putting t = 5 into this rate of change ,

we get, answer = 92.29
