At noon, ship A was 14 nautical miles due north of ship B. Ship A was sailing south at 14 knots (nautical miles per hour; a nautical mile is 2000 yards) and continued to do so all day. Ship B was sailing east at 7 knots and continued to do so all day. The visibility was 5 nautical miles. Did the ships ever sight each other?
Let the two ships meet each other after time t. The diagrammatic representation of the given problem is shown below.
The distance between them is evaluated as follows.
