This involves the concept of relativity and as a matter of fact, it might wish to concentrate the problem without outside disband retrieves it when the cork minutes. He then turns around, chasing the cork, tractions.

While rowing his boat upstream, Anik drops a cork overboard and continues growing for 10 more minutes. He then turns around, chasing the cork, and retrieves it when the cork has traveled 1 mile downstream. What is the rate of the stream? 


Rather than approaching this problem by the traditional methods, common in an algebra course, consider the following:

The problem can be made significantly easier by considering the notion of relativity.

It does not matter if the stream is moving and carrying Anik downstream, or is still. We are concerned only with the separation and the coming together of Anik and the cork.If the stream were stationary, Anik would require as much time rowing to the cork as he did growing away from the cork.

 

 

That is, he would require 10+10=20 minutes. Since the cork travels 1 mile during these 20 minutes, it's (i.e., the stream's) rate of speed is 3 miles per hour.

It is a concept worth understanding, for it has many useful applications in everyday life thinking processes.

here is a fun activity that can be presented in a number of different ways. The justification uses simple algebra, but the fun is in the oddity. Consider this very unusual relationship.

Einstein said that only 2% of the world could solve this problem.

 

There are 5 houses in 5 different colors. In each house lives a person with a different nationality. The 5 owners drink a certain type of beverage, smoke a certain brand of cigar, and keep a certain pet. No owners have the same pet, smoke the same brand of cigar, or drink the same beverage.

The Brit lives in the red house.

The Swede keeps dogs as pets.

The Dane drinks tea.

The green house is on the left of the white house.

The green homeowner drinks coffee.

The person who smokes pall Mall rears birds.

The owner of the yellow house smokes Dunhill.

The man living in the center house drinks milk.
