you have a 6 foot log, you need to cut it into 1 foot pieces. Each cut takes 1 minute, how long does it take to cut the log up.
Answer #1 6 minutes
Correct answer 5 minutes, the first cut will give you a 1 ft piece and a 5 ft piece, cut 2 will produce 2x one ft and a 4 ft piece... the last cut (number 5) will actually produce 2x 1 ft pieces for a total of 5 cuts, in 5 minutes.
Even more correct answer, 2.5 minutes, I do everything twice as fast as everyone else.
