It takes 120 minutes for a hose to fill a swimming pool. if the pool drain is open, it takes 360 minutes to fill the pool. if the pool is full, the hose is off, and drain is open, how many minutes does it take to empty the pool?

In those 360 the hose is working, and it's working the same as during the 120 when it filled the pool. Since 360 is three times 120, it means that it filled the pool three times this time. But the pool was only filled once!

This means that twice the pool was drained in those 360 minutes: this makes one draining every 180 minutes.

when we think of a­ncient paga­n kings, the ideas of justice and fairness probably aren't the first things to come to mind. we moderns may be more likely to imagine fickle, power-hungry despots who were ready to put someone to death on a whim. but king hammurabi, who ruled a prosperous and thriving babyloniaalmost four millennia ago, doesn't quite fit that mold. he claimed to have protect the weak from oppression, and scholars believe he fostered an atmosphere of justice and righteousness for his people.

this belief is based on an object that was discovered only a century ago. it has already earned a place alongside the rosetta stone as one of the most important artifacts of the ancient world. this stela (stone pillar) bears the inscription of the code of hammurabi, and it has shed light on the laws, culture and life in babylonia.
