Average Rate Of Work - Two Ditch Diggers
Strings (SiPjAjk) = S7P3A32 Base Sequence = 12735 String Sequence = 12735 - 3 - 31
A ditch-digger can dig a ditch in 2 days and another ditch-digger can dig the same ditch in 3 days. What is their average rate of ditch-digging per day?
S7P3A31 (Force - Pull).
Pj Problem of Interest is of type force. Problems of work are force problems.
Average rate of ditch-digging per day of first digger = 1/2
Average rate of ditch-digging per day of second digger = 1/3
Average rate of ditch-digging per day of both diggers = (1/2 + 1/3)/2 = 5/12.
The point . is a mathematical abstraction. It has negligible size and a great sense of position. Consequently, it is front and center in abstract existential reasoning.

The Universe is composed of matter and radiant energy. Matter is any kind of mass-energy that moves with velocities less than the velocity of light. Radiant energy is any kind of mass-energy that moves with the velocity of light.
