drilling another borehole: On a flat surface of land, geologists drilled a borehole straight down and hit a mineral deposits at 1000 ft. They drilled a second borehole 100 ft to the north of the first and hit the mineral deposit at 950 ft. A third borehole 100 ft east of the first borehole struck the mineral deposit at 1025 ft. The geologists have reasons to believe that the mineral deposi is n the shape of a dome, and for the sake of economy, they would like to find where the deposit is closest to the surface. Assuming the surface to be the xy-plane, in what direction from the first borehole would you suggest the geologists drill their fourth borehole?

Question
drilling another borehole:
On a flat surface of land, geologists drilled a borehole straight down and
hit a mineral deposits at 1000 ft. They drilled a second borehole 100 ft
to the north of the first and hit the mineral deposit at 950 ft. A third
borehole 100 ft east of the first borehole struck the mineral deposit at
1025 ft. The geologists have reasons to believe that the mineral deposi
is n the shape of a dome, and for the sake of economy, they would like
to find where the deposit is closest to the surface. Assuming the surface
to be the xy-plane, in what direction from the first borehole would you
suggest the geologists drill their fourth borehole?
