Strategies and Tricks to Solve Boat and Stream Question - Hitbullseye
The speed of boat upstream is equal to the difference of the speed of the boat in still water and speed of the myboat275 boatplans: Speed Downstream = B + S km/hr Speed Upstream = B � S km/hr. C++. // CPP program to find upstream and. // downstream speeds of a boat. #include. using namespace std; // Function to calculate the. // speed of boat downstream. int Downstream(int b, int s). { return (b + s); } // Function to calculate the. // speed of boat upstream. int Upstream(int b, int s). { return (b - s); } // Driver function. int main(). { // Speed of the boat in still water(B). // � Find speed of man from speed of stream and ratio of time with up and down streams. Formulas for Boats and Streams Questions with Basic Concepts. 1. What is Downstream: It is related to the direction of water flow in respect with the object, when the object or body is flowing in direction of stream it is called as Downstream. 2. What is Upstream: It is also related to the direction of water flow in respect with the object, when the object or body is flowing in opposite direction then the stream is called myboat275 boatplans boats and streams problems are based on the concepts of time, speed, and distance.� Let the speed of a man in still water be x km/hr and the speed of a stream be y km/hr. If he takes t hours more in upstream than to go downstream for the same distance, the distance travelled is. = (x2 � y2)*t. 2y. Additional Formulas of Boats and Streams 3. Speed of stream is = ? (Downstream Speed � Upstream Speed). Types of Questions asked in the Previous Exams By SSC. Type 1: When the distance covered by boat in downstream is same as the distance covered by boat upstream. The speed of boat in still water is x and speed of stream is y then ratio of time taken in going upstream and downstream is, Short Trick: Time taken in upstream: Time taken in Downstream = (x+y)/(x-y). Example: A Average Speed Of Boat In Upstream And Downstream Korean man can row 9km/h in still water.� Find the average speed of a boat in a round trip between two places 18 km apart. If the speed of the boat in still water is 9km/h and the speed of the river is 3km/h? Solution: Average speed = upstream * downstream / man�s speed in still water. Average speed = 6 * 12 / 9 = 8km/h.

Boats and Streams is an essential topic for many competitive exams. Many varieties of questions can be framed from this area. We use the fundamental concepts of time speed and distance only to solve elementary questions on Boats and Streams.

However, some types of questions are tricky and take lots of time to solve by applying textbook approach. Fortunately, there are some shortcut formulas available to handle such problems. In this article, besides an understanding of the basic concepts of boat sand streams, we will also learn few tricks to solve some exceptional questions. Some shortcut formulas related to the speed of boats and streams is handy as we require them frequently. Below are the lists of the formulas:. Question 1: A boat is rowed down a river 28 km in 4 hours and up a river 12 km in 6 hours.

Find the speed of the boat and the river. Question 2: A man rows 18 km down a river in 4 hours with the stream and returns in 12 hours.

Find his speed and also the speed of the stream. Question The speed of the boat in the still water is 6 kpmh, and the speed of the stream is 2 kmph.

The boat goes a certain distance down the stream and comes back upstream to the same place from where it started. Find the average speed of the boat in the entire journey.

Average Speed. Important: If the boat takes t down and t up respectively to travel same downstream and upstream distance, then we the following relation:. Question 4: A boat takes 6 hours to go downstream and comes back upstream in 12 hours. Find the ratio of the speed of the boat and the speed of the stream. Question 5: A man rows 10 km upstream and back again to the starting point in 55 min. If the speed of the stream is 2 kmph, then find the speed of the boat in still water.

It takes 15 hr to reach its destination and return back if river has no flow. For the same journey it takes 16 hr if river is flowing. Find speed of flow of river.

Boats and Streams � Terminologies: Stream: It implies that the water in the river is moving or flowing. Standard Method: Let one side the distance be d km.

Therefore, the average speed of the boat Shortcut Formula: Average Speed Finding the ratio of speeds of the boat and the stream Important: If the boat takes t down and t up respectively to travel same downstream and upstream Average Speed Of Boat In Upstream And Downstream Limited distance, then we the following Average Speed Of Boat In Upstream And Downstream Map relation: Question 4: A boat takes 6 hours to go downstream and comes back upstream in 12 hours. Standard Method: Let the common distance be d km. Finding the total time of the journey.

Shortcut Formula: Let the speed of the boat in still water be x kmph. Leave a Comment Cancel Reply Your email address will not be published. Join Now.
