1. Between the trains lies a short strech of track and a siding that is only long enough to hold one car or an engine. Each engine and car has a coupler at the end. Each train also has a brakeman who runs along the track to couple or uncoulpe designated cars.

1. Tussen de treinen ligt een klein stukje spoor en een parallel spoor groot genoeg voor één trein of wagon. Elke locomotief en wagon heeft voor en achter een koppeling. Iemand rent langs het spoor om te koppelen en te ontkoppelen.

 

2. Not only is the order of the engine and cars completely reversed but also the engine has been turned around and also each car.

2. Niet alleen de volgorde van trein moet omgekeerd worden, maar ook de locomotief en de wagons moeten elk omgekeerd worden.

3. The bridge is strong enough to hold one car but not the engine. The engineer must reverse the position of the cars. The bridge is no longer than a car, and the engine must be off the circular track when it has finished the job.

3. De brug kan wel een wagon houden, maar niet de locomotief. De machinist moet de wagons verwisselen. De brug is niet langer dan een wagon. De locomotief moet uiteindelijk buiten de cirkel zijn.

4. On a train, Smith, Robinson, and Jones are the fireman, brakeman, and the engineer, but NOT respectively. Also aboard the train are three businessmen who have the same names: a Mr. Smith, a Mr. Robinson, and a Mr. Jones.

  1. Mr. Robinson Lives in Detroit.

  2. The brakeman lives exactly halfway between Chicago and Detroit

  3. Mr. Jones earns exactly $20,000 per year.

  4. The brakeman's nearest neighbor, one of the passengers, earns exactly three times as  much as the brakeman.

  5. Smith beats the fireman in billiards.

  6. The passenger whose name is the same as the brakeman's lives in Chicago.

Who is the Engineer?

5. Two trains travel toward each other on the same track, beginning 100 miles apart. One train travels at 40 miles per hour; the other travels at 60 miles an hour. A bird starts flight at the same location as the faster train, flying at a speed of 90 miles per hour. When it reaches the slower train, it turns around, flying the other direction at the same speed. When it reaches the faster train again, it turns around -- and so on. When the trains collide, how far will the bird have flown?

6. Isaac and Albert wanted to take a vacation. They were debating how they could get to their hotel in the fastest manner. Isaac said, "We should go by train." But Albert said, "No, the train reaches the end of the line half way to the hotel -- we would have to walk the rest of the way. We should bike to the hotel instead." Isaac disagreed. So Albert biked the whole way to the hotel, while Isaac took the train for the first half of the journey and walked for the remainder.

The speed of the train turned out to be four times that of the bike's speed. The bike's speed turned out to be two times faster than walking speed. Who got to the hotel first?
