Dear Reader, problems under boats and streams are not only easy to solve but interesting as. Speed of stream questions uk this tutorial, you will see 5 important types of problems. At the end of the tutorial, you will find short online practice test.

Let us begin the tutorial. In this type, you will be questiona speed of boat in still water i. You have to remember a very simple formula as shown. Find the speed of speed of stream questions uk boat in still water. Solution: From the question, you can write down the below values.

You have to substitute the above values in the below formula. This type is similar speex type 1. But there is one difference. Here you have to find speed of stream and not the speed of the boat. You have to use the below formula to find speed of stream. Example Question 2: A man rows downstream 30 km and upstream 12 km. If he takes 4 hours to cover each distance, then the velocity of the current is:.

Solution: In this question, downstream and upstream speeds are not given directly. Hence you have to calculate them. Step 3: Calculation of speed of stream You have to substitute values got in steps 1 and 2 in below formula to find the speed of the stream.

In this type, you have to find distance of places based on given conditions. Below example will help you to understand better. If in a river running at 2 km an hour, it takes him 40 minutes to row to a place and return back, how far off is the place? The man rows to a particular place and comes. You have to calculate the distance of this place. Let this distance be X. See the below diagram to understand clearly. Man starts from Speed of stream questions uk, travels to B and comes.

Therefore, above equation becomes. Also we have calculated downstream and upstream speeds at the questinos see values 1 and 2.

In question, you can see that the man takes 40 minutes to travel to B and come back to Speed Speed Of Stream Questions Names of stream questions uk. You have to convert this to hours and apply in above equation. We are converting from minutes to hours because we are using speed values in km per hour units. It takes him twice as long to row up as to row down the river.

Find the rate of the stream. Solution: Step 1: Calculate upstream and downstream speeds. Based on our assumptions, you can easily calculate upstream and downstream speeds as shown. In this type, you have to form linear equations based on conditions given. You have to solve those equations to find the answer.

Example Question 5: Kavin can row 10 km upstream and 20 km downstream in 6 hours. Also, he can row 20 km upstream and 15 speed of stream questions uk downstream in 9 hours.

Find the rate of the current and the speed of the man in still water. Solution: You have to make below s;eed to form equations. You already know the below equation.

If you are not clear about this, refer to the equation in type 3. Note: To solve such strea equations, there is another simple speed of stream questions uk. Here is the video link to that shortcut. From the values of u and v, you can find the downstream and upstream speeds as shown. Also, you know the formula for speed Speed Of Stream Questions 901 of the current.

Stream Boat Problems Practice Questions. Let us start by recalling some of the formulas for this section. Suppose the speed of a certain boat in still water is �u� km/hr and the speed of the stream is Speed Of Stream Questions Java �v� km/hr, then: Speed of this boat downstream = (u + v) km/hr. Speed of this boat upstream = (u -v) km/hr. Sep 13, �� If the speed of the man in still water is Z km/hr then the speed of the stream will be Let us now jump to the questions, 1. In still water speed of boat is 8 km/hr. Find the upstream speed of boat which is floating in the sea where speed of waves is 3 km/hr. 5. A car travels at 88 km/hr over a distance of 22 km. Find in minutes the time taken for the car to travel this. 4 minutes. 15 minutes. minutes.
