Pyramid Maneuver (Posted on 2012-12-06)

A walking track is constructed over the surface of a pyramidal structure having a square base of side 100 feet and base angles of the inclined faces equal to 60 degrees each. The track was laid as the shortest path from one corner of the base to its opposite one.

Is it feasible for a traveller who cannot negotiate a slope stiffer than 1 in 2 to undertake and finish walking uphill along the track?

A typo and a minor question.

In the line "The path sought is the altitude from A to MB, call the point it hits MB by H." the MBs should be XBs.

Why did you use right triangle AYP to find AP instead of right triangle APH ?
