10. Ball in the Pipe A swimming pool has a cover that is supported by two heavy metal pipes in the walkway around the pool. One day when the cover supports are removed a tennis ball falls into one of the pipes. This metal pipe is two feet long, and is embedded into the concrete by the pool and cannot be moved. The pipe is vertical. At the bottom of the pipe is the tennis ball. The ball just fits inside the pipe. You cannot get your hand down into the pipe to retrieve the ball. Here is what you have available to you.

17. Two trains stations are 50 miles apart. At 1 pm on Sunday, a train pulls out of each station and the trains start toward each other. Just as the trains pull out from the station, a hawk flies into the air in front of the first train and flies ahead to the front of the second train, it turns around and flies towards the first train. The hawk continues in this way until the trains meet. Assume that both trains travel at the rate of speed of 25 miles per hour and the hawk flies at constant speed of 100 miles per hour. How many miles will the hawk have flown when the trains meet? Changing the representation of the problem

Just as the trains pull out from the station, a hawk flies into the air in front of the first train and flies ahead to the front of the second train, it turns around and flies towards the first train. The hawk continues in this way until the trains meet. Assume that both trains travel at the rate of speed of 25 miles per hour and the hawk flies at constant speed of 100 miles per hour. How many miles will the hawk have flown when the trains meet? Most people approach this problem as one of distance. Instead change the representation and make it a problem of time. The trains will travel one hour until they meet, the hawk can travel 100 miles in one hour, therefore the answer is 100 miles.
