There are a variety of subconcepts which are related to answering questions based on boat and streams. Given below are the four terms which are important for a candidate to know to understand the concept of streams.\tStream –\xa0The moving water in a river is called stream.\xa0\tUpstream –\xa0If the boat is flowing in the opposite direction to the stream, it is called upstream. In this case, the net speed of the boat is called the upstream speed\tDownstream –\xa0If the boat is flowing along the direction of the stream, it is called downstream. In this case, the net speed of the boat is called downstream speed\tStill Water –\xa0Under this circumstance the water is considered to be stationary and the speed of the water is zero
The terms\xa0upstream and downstream\xa0oil and gas production refer to an oil or gas company\’s location in the supply chain. Upstream\xa0oil and gas production is conducted by companies who identify, extract, or produce raw materials.\xa0Downstream\xa0oil and gas production companies are closer to the end user or consumer.When a boat travels in the same direction as the current, we say that it is traveling\xa0downstream. Thus if b is the speed of the boat in still water, and c is the speed of the current, then its total speed is.\xa0Downstream\xa0speed = b + c. When a boat travels against the current, it travels\xa0upstream.
