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

The rate of change of distance is -

after putting t = 5 into this rate of change ,
we get, answer = 92.29
