Boats & Stream Tricks with Questions - BankExamsToday
Derivation of formula 8 (boats and streams). Let the speed of a man in still water = $x$ km/hr speed of the stream = $y$ km/hr. Assume he travels a distance $d$ km upstream and come back the same distance downstream, and total time taken = $t$ hours. Speed downstream $=(x+y)$ Speed upstream $=(x-y)$. Time taken to travel upstream $=\dfrac{d}{x-y}$ Time taken to travel downstream $=\dfrac{d}{x+y}$. Total time $=t$ $\dfrac{d}{x-y}+\dfrac{d}{x+y}=t\\ d(x+y)+d(x-y)=t(x+y)(x-y)\\ 2dx=t(x+y)(x-y)\\ 2dx=t(x^2-y^2)\\ d=\dfrac{t(x^2-y^2). }{2x}$. If what you want is driving distance (or biking distance or public transportation distance or walking distance), you'll have to use a mapping API (Google or Bing being the most popular) to get the appropriate route, which will include the distance. Incidentally, the Google Maps API provides a packaged method for spherical distance, in its myboat315 boatplanscal namespace (look for computeDistanceBetween). It's probably better than rolling your own (for starters, it uses a more precise value for the Earth's radius). For the picky among us, when I say "straight-line d. Buffers in streams. Stream and event emitters. A read stream. Flowing and non-flowing read stream. Buffer management by the read stream. Types of Streams.� Read Streams in myboat315 boatplans A stream that is used to read the streaming data is called a read stream. A read stream can be reading a file from a server, or streaming an online video.

Hey I am Ramandeep Singh. Do you want me to help you? Login Sign Up. Formula 1: If the ratio of downstream and upstream speeds is D: U, then ratio of time taken will be U : D. Question: A boat running upstream takes 8 hours 48 minutes to cover a certain distance, while it takes 4 hours to cover the same distance running downstream. What is the ratio between the speed of the boat and speed of the water current respectively?

Solution: When 8 hours 48 minutes is written using mixed fractions,. Therefore, the ratio of the time taken becomes Which on solving gives, Now, as the ratio of time is inversely proportional to that of Upstream and Downstream speeds.

Now, the ratio of speed of boat and the speed of stream will be. How far is the place? Solution: Take out the formula book. A man rows a certain distance downstream in X hrs and returns the same distance in Y hrs. Question: Ramesh can row a certain distance downstream in 6 hrs and returns the same distance in 9 hrs. Formula 4: A man rows a certain distance downstream in X hrs and returns the same distance in Y hrs. Let us now jump to the questions, 1.

A boat covers a distance of 30 km in 3 hrs in the direction of stream and covers same distance in 5 hrs in opposite direction of the stream. Find speed of the boat in still water. Therefore, in how much time will it cover a distance of 70 km downstream?

Find out his speed in still water. How much distance does he cover in 2 hrs during upstream? How much time will it take to cover km in still water? A man rows to a place at a distance of Find the total time taken by him. A man rows upstream 16 km and downstream 28 km taking 5 hours each time. Find the velocity of the current. A can row a certain distance downstream in 6 hrs and return the same distance in 9 hrs.
