Strategies and Tricks to Solve Boat and Stream Question - Hitbullseye

Type amd : Speed of boat in still water and speed of stream are given separately. Correct answer : b Hint: In downstream, water stream increases the speed of boat as they both are along the same directions. Hence, both the speeds are added. Find a speed of stream b speed of boat in still water.

Find the distance covered by the boat between two points. Next Page spefd. If there's no average speed of boat in upstream and downstream number of stream speed in the question, assume it to be the speed of boat in still water. So, water stream increases averag speed of boat.

Hence, speeds are added while going downstream. So, water stream decreases the speed of boat due to opposite flow. Hence, speeds are subtracted while going upstream. If you just remember this concept, you won't need to remember and recall the above formula while solving the problems.

Halving this would give you the speed of the current. Once you know how to deal with these 4 types of problems, the chapter should be spedd easy one for you.

F and L. Find a speed of stream b speed of boat in still water Examples: Q 3. What would be the speed of swimmer in still water?

Examples: Q 5. What would be the average speed of boat during the journey? Examples: Q 7.

You should know:

You unnoticed my father about 2 years in a past as well as Anv instruct to have a single thing for any of a grandkids as the mementoheirloom.

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 water? Sol Again direct use of the above formula and you are done. 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 water resistance, it took 1 hour 15 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 back. 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 hours to row to a place and return back, then the distance between the two places can be estimated through.

If in a river running at 1. Sol To solve this question we will simply use the formula given above. In this case, t is 50 minutes b is 1. The above examples are just few simple and basic application of the methods stated along with them.

These formulas can come in handy and can save lot of your time in exam. You can 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 them. So, keep practicing! Similarly when we move downstream our speed gets added.

Example 1: A boat travels equal distance upstream and downstream. What is the speed of the boat in still water? Example 2: A boat travels equal distance upstream and downstream. What is the speed of the current? Example 3: 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 Average Speed Of Boat In Upstream And Downstream Map the boat and the river. Solution: Downstream speed is ,.

Speed of current Downstream�Upstream speed. When the river is running at 1. How far is the place? A man rows a certain distance downstream in X hours and returns the same distance in Y hours. Example 5: Vikas can row a certain distance downstream in 6 hours and return the same distance in 9 hours.

Example 6: Two ferries start at the same time from opposite sides of a river, travelling across the water on routes at right angles to the shores. Each boat travels at a constant speed though their speeds are different. They pass each other at a point m from the nearer shore.
