Average Rate Of Work - Two Ditch Diggers
Math 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?

The string:
S7P3A31 (Force - Pull).
The math: 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.
