Our assumption: A to B is 6 miles, as in the note to the solution; the exercise drawing shows 5. With 5 miles it takes about 74 minutes and you arrive at about 1114.
You have to go from A to B, 6 miles due north. The boat makes 3 knots and the stream sets 045° at 2 knots. You leave at 1000. What course must you steer, and what time do you arrive?
- Ground track A-B
- 000°, 6 NM
- Boat speed
- 3 kn
- Tidal stream
- 045°, 2 kn
- Departure
- 1000
Solution worked out by us from the course material: to be checked by the instructor.
