There is a detailed scientific formula that can be done to determine the answer to this question based on when the person last ate, when their first and last drink was, and what the BAC was, HOWEVER, absent all of that information, most people accept that the average person eliminates .02 per hour.
Therefore, if you were at the legal limit of .08, it would take the average person 4 hours to have no detectable alcohol in their system.
Added: Perhaps a simpler, easier to understand method of calculation . . . the average adult body can process and metabolize apoproximately 1 ounce of alcohol every hour.
4 ÷ 2 = 2 so each piece measures two feet in length.
If the cut is parallel to the long dimension, then each piece is 40 inches long, but its width is 1/2 of the original board's width. If the cut is parallel to the short dimension, then the width is preserved, and each piece is 20 inches long. If the cut is parallel to to the flat, then each piece is 40 inches long and has the original width, but is only 1/2 the thickness of the original board.
A 102 centimmeter board is cut into two pieces so that one piece is five times as the other . How long is each piece
This will depend on how long you would like each piece to be. If each piece is to be 1 inch long, then 115 pieces could be cut. If each piece is 2 inches long, then 57 pieces with 0.5 inches left over If each pieces is 5 inches long, then 23 pieces and so on and so forth.
One hour each beer do the math
Each piece of string is :1/7 x 20 = 2 6/7 or 2.857 inches (3dp)
19.6 / 4 = 4.9 inches per piece.
lengths are x and 4x so 5x = 15.5 making x = 3.1m and the longer piece 4 x 3.1 = 12.4m

Convergent thinker
one fifth is 3.2m. so one three-fifths piece is 9.6m and the two-fifths piece is 5.4m
