Question 466990
Well, you are on the right track but you made a slight mistake:
The total distance north from point A is: 3km-1km = 2km. (Not 3km)
The total distance east from point A is 2km+4km = 6km
The distance from point A to B (call this d) is:
{{{d = sqrt(2^2+6^2)}}}
{{{d = sqrt(40)}}}
{{{d = 6.3}}}km.
