# Old MadDonalds Farm

Out in the backwoods of southern Madadia lives Old MadDonald, he has a farm. And on that farm he has several types of livestock.

He had a the Famous Madadian Southern fried Chicken, (the one with six legs and no breast)

The equally well known Madadian self basting Turkey and also the amazing Duck La Orange.

Old MadDonald lived alone and as a result became extremely bored at times and thus always tried different ways to amuse himself, some of them legal. One such way was to race the poultry livestock against each other.

The Southern Fried Chicken could fly at 5 mph but, as chickens are poor flyers and it had little in the line of muscle across its breast, it gets tired very soon. After only 2 minutes of flying, it has to walk at 1 mph for next three minutes before it could attempt to fly again.

The Self Basting Turkey could fly continuously at 4 mph, but he had a habit of swerving back and forth. So for every 3 feet he flies, he actually only travels 2 feet.

The Duck La Orange could fly straight and continuous at 2mph.

Which of the three of Old MadDonalds Birds would win a race over a distance of one mile ?

### Answer

Surprisingly the Southern Fried Chicken would win the one-mile race.If you were to calculate the average speed, you'll see that the chicken's average speed, after 5 minutes, is 2.6 mph.

The Self Basting Turkey's average speed is 2.67 mph.

The Duck La Orange, as stated above, has an average speed of 2 mph.

Based on this information alone it appears that the Self Basting Turkey should win.

The catch is the fact that the one-mile race does not take an even multiple of five minutes to complete. The Southern Fried Chicken's average speed is only accurate after the full five minutes of flying/walking is completed. At any time before that, the chicken's mean speed will be higher.

After 20 minutes have passed, the Southern Fried Chicken will have traveled a total of 0.87 miles, and the Self Basting Turkey will have traveled a distance of 0.89 miles. However, the S.F Chicken will then begin flying at 5 mph, and will overtake the S.B.Turkey.

The final results will be:

1. Southern Fried Chicken - 21.6 minutes (21 minutes 36 seconds)

2. Self Basting Turkey - 22.5 minutes (22 minutes 30 seconds)

3. Duck La Orange - 30 minutes

Thank you, well done, a very fun and educational teaser.

I enjoyed it.

good teaser mad. Are you going to share some of that chicken adn self basting turkeY?

From your other teasers, I've gathered that another relevant question is: How many kebabs does each animal yield? Fun teaser.

Good one! You got me. I based my calculations on 5 hours of flying time and I thought I had taken into account the variation. Big mistake. The Turkey would fly the farthest in 5 hours but I forgot that when you average it out, it won't be a full cycle for the Chicken. Smart!

I read it over twice, thought for a moment, and guessed correctly! Good teaser!
