Answer :

First, the one minute person and the two minute person must cross the bridge, for a total of two minutes. Then the one minute person should come back with flashlight - total of three minutes. The five minute person and the ten minute person cross together next, making the total thirteen minutes. Now the two minute person goes back and (total now fifteen minutes) and gets the one minute person and they cross together bringing the total to seventeen minutes.

There are two cliffs. They are each attached by a suspension bridge that takes 5 minutes to walk across, and is the only way to get to the other side. No one is allowed to cross the bridge unless authorized. There is a guard on the other side that takes a nap every 5 minutes, then keeps watch for 5 minutes, takes a nap for 5 minutes, and so on. Let's say you don't have authorization. How would you get across (Remember, he wakes up EXACTLY after 5 minutes, meaning if you go on the bridge the second he takes a nap, and you cross the bridge, he'll wake up exactly when you reach the other side, and send you back)? -Riddles

In the early 1900’s in England, there was two towns: town A and town B, and there was a huge river in between them. The only way across to each town was by a long bridge with a guard post in the middle. It took 20 minutes to cross the bridge from one side to the other and 10 minutes each way from the guards tower. There were no hiding spots on the bridge so people couldn’t sneak past, and the guard comes out every 5 minutes or so to check to see if anyone is trying to cross. The guards tower was placed because of a law that stated that no one was aloud to leave their own town into the other because of political reasons and anyone who was caught by the guard would be fined and told to turn back. Many people have tried to cross but have always been caught, even very fast runners have only ab

The closed circulatory system is more efficient. Since blood circulates only inside blood vessels it can do it with more pressure reaching farther distances between the organs where hematosis happens and the peripheral tissues. In addition the circulatory speed also heightens making possible more oxygen supply to great consuming tissues, like the muscle tissues that then can perform faster movements. Animals with an open circulatory system (with the exception of insects that do gas exchange independently from the circulation) are generally slower and have a low metabolic rate.
