Boats and Streams - Aptitude test, questions, shortcuts, solved example videos

This a very simple topic and mere require direct application of formulas to solve the question. However, many students find this topic confusing and find face difficulties in solving. And, the reason for facing such hindrance is the understanding of the language of question. They are just SpeedDistance and Time questions in water rather with a strream twisted language.

Upstream : It means that you are moving in opposite direction from that in average speed of boat and stream 10 river flows. Example 1: The speed of a motor boat is that of the stream as The boat goes along with the stream in Average Speed Of Boat And Stream 150 5 hours and 10 minutes. How much time will it take to come back? What is the speed of the boat in still water and the speed of the stream?

Speed-based questions also include one more type in which time taken and distance covered is given along with speed of stream is given then you can find the speed of the boat in still water using following formula:.

Example 3: A boat take 8 hours to cover a distance while traveling upstream, whereas while traveling downstream it takes 6 hours. What is the speed of the boat in still speee Sol Again direct use of the above formula and you are. Example 4: A boat, while going downstream in a river covered a distance of 50 miles at an average speed of 60 miles per hour.

While, returning because of blat resistance, it took 1 hour average speed of Average Speed Of Boat And Stream 4d boat and stream 10 minutes to cover the same distance. What was the average speed during the whole journey? Sol In this problem we cannot directly use the formula first we need to find the upstream speed and speed in still water. This can be done as follows. Example 5: A person challenged himself to cross a small river and. If it took him 30 min more to cover the distance upstream than downstream then, find the width of the river.

If a boat takes t average speed of boat and stream 10 to row to a place and return back, averaeg average speed of boat and stream 10 distance between the two places can be estimated.

If in a river running at 1. Sol To solve this question we will simply use the formula given. In this case, t is 50 minutes b is 1. The above average speed of boat and stream 10 are just few simple and Average Speed Of Boat And Stream Quality basic application of the methods stated along with.

These formulas can come in handy and can save lot of your time in exam. You boatt find questions and problems involving simultaneous use of more than one formula at times.

But if you know the correct utilization of them you can solve any problem easily. And, this smoothness comes with practice so the more you varied questions you try the more you will learn and become better at solving. So, keep Average Speed Of Boat And Stream Dog practicing!

Downstream : It means moving averate in the direction of the flow of the stream.

There can also strram other questions in calculation of time and some of them can be easily be solved using the formulas given. Let d the distance. Sol This question requires direct use of the formula mentioned earlier. Average Speed-based question: As the name tells, we need to calculate the average speed of the boat while you are upstream and downstream speed.

Now we are in stage of using the average speed formula. Distance based question: In these kind, you have to calculate distance travelled by the boat when time, speed of still water and stream is given. There can be two different formulas to calculate the distance for two distant cases. If you Like this post then share it! Leave a Reply Cancel reply Your email address will not be published.

These rods could be of any element ! I pulled a front apportionment of a rasied rest room partial to display a H2O line. Great we have been not allergic to shrimp any more as most as you're penetrating upon them or is it only a boats.

The speed limit for boats is rarely a specific numerical figure. Most speedboats and other motorboats can cause a wake in as little as 5 MPH. If you are close to a river, shore, or populated areas, you have to tread on the side of caution. It can go about 57 MPH or 50 knots! It is an all-aluminum speed demon with two MTU diesel engines, which propel it forward at a whopping The triple waterjets MTU 16V M90 series push it forward with 11, hp, making it fly across the water at a top speed of This yacht tops out at 69 mph because of her three gas turbine engines.

Together, they generate about 13, horsepower. In addition to that, she also has two conventional engines to help her move around the water a little easier when she needs to cruise at a slower speed. The Kereon is an She has three 2, horsepower CRM diesel engines that were designed by Angelo Arnaboldi, a naval architect.

The Kereon can accommodate six guests in three cabins. She also has a massive fuel tank, which can hold gallons of fuel. That means she can go approximately nautical miles on one tank of fuel. Question Variety: Type 1 : Speed of boat in still water and speed of stream are given separately.

Find a speed of stream b speed of boat in still water Examples: Q 3. 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. Your email address will not be published. Skip to content Boats and Streams is an essential topic for many competitive exams.

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 distance, then we the following 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.
