For this edition of Flashback Friday, we want to give your brain a workout with a few classical or original puzzles from ** The 1993 Old Farmer’s Almanac**. Everyday common sense and a little agility are all you’ll need; you won’t need calculus, computers, alertness to tricks, or specialized knowledge. The answers to each of the puzzles appear below.

Ready? Set. Go!

*Wet Matches*

Noah’s harbor agent phoned Noah that he was sending out a herd of 5 male and 6 female zebras. Soon the 11 animals randomly swam up to the ark. What is the largest number that Noah might have to fish out to be sure he embarked one of each gender?

**Puzzle #2**

An auto traveled one mile at 30 miles an hour. How fast would it have to travel another mile in order to average 60 miles an hour for the two miles?

**Puzzle #3**

*Make Your Own*

a.) Choose any number between two and 28, divisible by three. Multiply by 37. Add 241,000. Add the six digits together, forming a two-digit sum. From this sum, subtract your original choice. What is your answer?

b.) Choose any number at all. If even, divide it by two; if odd, multiply it by three and add one. Do the same to the result and keep repeating. What is the last number before the series repeats.

**Puzzle #4**
