thx but i dont rili get part a)
where did the 6j come form?

[astarmathsandphysics]

Do you mean 6i

[Saladin]

The pipeline is known to run north-south for a long distance through the
point with position vector 6i km


This means that it passes through 6i and also it passes through it in a north south direction, and this it will pass through the point 6j, and thus, as the pipeline is south west of him, he is higher up than the pipeline, and this 6j+2j=8j

hope that explains it.
