EWB is one of these types of organizations that help people around the world.
What is Humanitarian? or What is Humanitarian Organization?
FACTS: EWB-USA was formed in 2002 after a University of Colorado Boulder professor visited a community in Belize and learned that they lacked clean water and sanitation infrastructure. As a result, the local children spent a majority of their time carrying water for drinking and crop irrigation from miles away. The professor connected the engineering skills of his students with the community in San Pablo to create a mutually beneficial partnership to come up with a solution. There are now hundreds of college and professional chapters across the US that work with communities in developing countries to improve public health.

The widest cable-stayed bridge in the world is the Leonard P. Zakim Bunker Hill Bridge, located in this city.
What is Boston?
FACTS: The "Zakim Bridge", also known as the "Bunker Hill Bridge", and connecting tunnel were built as part of the Big Dig which is the largest highway construction project in the United States. We can't fully appreciate this structure without understanding all the symbolism it contains. An example of this is the tops of the two upside-down-Y-shaped towers, which are meant to mimic the nearby Bunker Hill Monument. The Bunker Hill Monument marks the location of one of the first major battles of the American Revolution.

What are EWB chapters?
FACTS: EWB student chapters are located at colleges & universities across the country to support engineering students who are interested in working on projects to improve public health around the world. EWB professional chapters include people of all disciplines, not just engineering - for example - geologists, hydrogeologists, teachers, and toxicologists. They all contribute to the success of EWB projects around the globe.

What is the metric system?
FACTS: The metric system uses units such as meter, liter, and gram to measure length, liquid volume, and mass, just as the U.S. customary system uses feet, quarts, and ounces to measure these. The system was first proposed by the French astronomer and mathematician Gabriel Mouton in 1670 and was standardized in France under the Republican government in the 1790s.

Taylor is five times as old as Spencer. The sum of their ages is eighteen. How old are Taylor and Spencer?
What is Taylor is 15 years old and Spencer is 3 years old?
SOLUTION: Let x represent Spencer's age.
Therefore, Taylor's age is 5x. x + 5x = 18
6x = 18; x = 3
