Quiz Answer

22 April, 2021

The answer is obtained from the formula for a right angle triangle with sides measuring in the ratio of 3, 4 and 5 units in length.

When halfway, your log tells you that you have travelled 8 miles through the water (A/B). However, with the tide taking you 6 miles at right angles to your course (B/C), the actual distance travelled will be 10 miles (A/C).
As you are half way it is fair to assume that the distance to your destination will also be 10 miles.
If you are lucky, it will be either high or low water and the tide will turn in the opposite direction at approximately the same rate. In which case you would probably be able to continue on the same heading.
If not, you will need to get the tide tables and navigation instruments out to calculate what your new course to steer will be, cursing as to why you did not do it all before you left your berth.
