A pipleline must be laid to form a straight line along the shore joining the refinery (150,305) to the harbour at (215,-20). A second pipeline is to be laid underwater from an offshore drilling platform located at (210,57) to the first pipeline, at the closest point on the shore. The scale of the grid used for locating the poiints above is in kilometers.
Calculate the distance the oil will flow from the offshore platform to the refinery.
I would really appreciate it if someone can help me on this. The one thing i need to know if how to find the distance to the offshore platform. Thanks alot!
