## FAQs on Tips & Tricks: Boats & Streams Video Lecture - Quantitative Aptitude for SSC CGL

 1. What is the concept of boats and streams in mathematics?
Ans. Boats and streams is a concept in mathematics that deals with the relative speed of a boat moving in a stream. It involves calculating the speed of a boat in still water, the speed of the stream, and how these factors affect the boat's movement in different directions.
 2. How do you calculate the speed of a boat in still water?
Ans. To calculate the speed of a boat in still water, you need to know the distance traveled by the boat and the time taken. Simply divide the distance by the time to get the speed. This can be represented by the formula: Speed = Distance/Time.
 3. How does the speed of a stream affect the boat's speed?
Ans. The speed of a stream affects the boat's speed when moving against or with the stream. If the boat is moving against the stream, the effective speed of the boat is reduced by the speed of the stream. Conversely, if the boat is moving with the stream, the effective speed of the boat is increased by the speed of the stream.
 4. How do you calculate the speed of a boat when moving against the stream?
Ans. To calculate the speed of a boat when moving against the stream, subtract the speed of the stream from the boat's speed in still water. This can be represented by the formula: Boat's Speed = Speed of Boat in Still Water - Speed of Stream.
 5. Can the speed of a stream ever make the boat's effective speed negative?
Ans. No, the speed of a stream cannot make the boat's effective speed negative. Even if the speed of the stream is faster than the speed of the boat in still water, the boat will still have a positive effective speed. However, the boat's effective speed may be reduced to zero if the speed of the stream is equal to the speed of the boat in still water.
