How do you measure the distance between a boat and stream?
Important Formulas – Boats and Streams speed of the stream =y = y km/hr. Let speed of a man in still water =x = x km/hr, speed of the stream =y = y km/hr, distance =d = d km.
How do you calculate average speed in a boat and stream?
{(Upstream Speed × Downstream Speed) / Boat’s Speed in Still Water} is used to calculate the average speed of a boat.
Which is the correct formula for finding the speed of boat?
Upstream = (u−v) km/hr, where “u” is the speed of the boat in still water and “v” is the speed of the stream. Downstream = (u+v)Km/hr, where “u” is the speed of the boat in still water and “v” is the speed of the stream.
What is the formula for finding the speed of boat in still water?
Speed of the boat in still water = b (t2 + t1)/ (t2 – t1) km/hr. Example 3: A boat take 8 hours to cover a distance while traveling upstream, whereas while traveling downstream it takes 6 hours. If the speed of the current is 4 km/hr.
How do you calculate stream rate?
Upstream and Downstream – Formula
- Upstream = (u−v) km/hr, where “u” is the speed of the boat in still water and “v” is the speed of the stream.
- Downstream = (u+v)Km/hr, where “u” is the speed of the boat in still water and “v” is the speed of the stream.
- Speed of Boat in Still Water = ½ (Downstream Speed + Upstream Speed)
What are some examples of boat and stream questions?
Given below are a few sample boat and stream questions with solutions that may help you understand the concept better. Q 1. A person can swim in water with a speed of 13 km/hr in still water. If the speed of the stream is 4 km/hr, what will be the time taken by the person to go 68 km downstream? To travel 68 km downstream. Q 2.
What is boat and Stream concept in government exams?
The boat and stream concept is one of the most common topics based on which questions are asked in the various Government exams conducted in the country. The boat and stream questions are asked in the quantitative aptitude section of the Government exams and the weightage of questions mostly varies between 1-3 marks.
How do you calculate the aggregate speed of a boat?
Hence Aggregate Downstream Speed = b + s kmph. (Boat is moving with the steam of water). Upstream Net Speed = b – s km/hr. (Boat is moving against the direction of the stream). (Proved as per the assumption). Speed of boat is always greater than the speed of the stream.
How do you find the speed of a boat going upstream?
Let one side the distance be d km. Similarly, Upstream speed = 6-2 = 4 kmph. 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.
